Witch Doctor
* Luna can easily cancel channeling spells with 
Lucent Beam and 0.25s Eclipse Lucent Ministun talent for 
Eclipse, she can also buy 
Abyssal Blade in case they decide to buy 
Black King Bar: 
Enigma's 
Black Hole, 
Witch Doctor's 
Death Ward, 
Shadow Shaman's 
Shackles, 
Lion's 
Mana Drain, 
Bane's 
Fiend's Grip, 
Pudge's 
Dismember, 
Crystal Maiden's 
Freezing Field, 
Pugna's 
Life Drain, 
Dawnbreaker's 
Solar Guardian, and 
Naga Siren's 
Reel In from 
Aghanim's Scepter.
Additional:
* Lucent Beam interrupts Death Ward from a decent range.
* With Dust of Appearance, Eclipse kills Witch Doctor during Death Ward, even through 
Glimmer Cape.
Dawnbreaker
* Luna can easily cancel channeling spells with Lucent Beam and 0.25s Eclipse Lucent Ministun talent for Eclipse, she can also buy Abyssal Blade in case they decide to buy Black King Bar: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.
Witch Doctor
* 
Guardian Angel protects allies from Death Ward's physical damage.
* 
Purification and 
Heavenly Grace will most likely save teammates from dying to Maledict.
Witch Doctor
* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with 
Fate's Edict and 
Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with 
False Promise.
Witch Doctor
* Wraithfire Blast cancels Death Ward in decent range.
* Death Ward is meaningless while Reincarnation is off cooldown.
* Vampiric Aura can out-heal the {tooltip:DoT|Damage over Time} from 
Maledict.
Witch Doctor
* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.
Dawnbreaker
* Being a strength hero with a high strength gain means 
Feast can give her a hard time,especially later in the game.
* However,
Starbreaker's physical damage can control him in the laning phase.
Dawnbreaker
* 
Kinetic Field prevents Dawnbreaker from escaping with Celestial Hammer.
* Kinetic Field and 
Static Storm can pin down Dawnbreaker after she jumps in with Solar Guardian.
* 
Glimpse can force Dawnbreaker out of a fight right after she uses Solar Guardian.
Witch Doctor
* 
Kraken Shell dispels the stun from Paralyzing Cask. However, it does not dispel the damage from Maledict.
* Once Witch Doctor first uses his Death Ward in team fights, Tidehunter can simply cancel it with 
Ravage, turning the tables against him, especially if Witch Doctor does not have a Black King Bar.
* As a precaution, Witch Doctor should let Tidehunter use Ravage first before channeling Death Ward to turn a team fight in his favor.
Witch Doctor
* Like any hero with a channeled spell, 
Last Word is a counter to it.
* 
Global Silence goes through spell immunity and prevents Witch Doctor from casting his spells.
Witch Doctor
* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with 
Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.
Dawnbreaker
* 
Gust can shut down most of Dawnbreaker's abilities, rendering her useless.
* 
Frost Arrows followed by a high attack speed, makes it hard for Dawnbreaker to escape.
Witch Doctor
* Beware of placing the Death Ward if 
Chronosphere is off cooldown, as it will cancel the effect and leave Witch Doctor vulnerable if he does not react in time.
Dawnbreaker
* 
Time Walk can easily avoid Dawnbreaker's abilities or to escape her gank attempts and backtrack any damage she deals.
* 
Time Dilation can prevent Dawnbreaker from using her abilities after initiating, and slowing her down severely.
* 
Time Lock combined with his high attack speed can lock Dawnbreaker in place, preventing her escape with Celestial Hammer.
* Chronosphere locks down Dawnbreaker in place right after she uses Solar Guardian.
* On the other hand, if Solar Guardian is cast beforehand from afar, it may discourage Faceless Void from casting Chronosphere in its location
Dawnbreaker
* Solar Guardian can heal allies that trapped inside Chronosphere.
Witch Doctor
* Witch Doctor's iconic Death Ward is a perfect spell for Rubick to output high damage.
* Death Ward requires channeling which makes Witch Doctor a clear tagret for stealing. Rubick can steal the spell outside of Death Ward's attack range most of the times.
* Note that an skilled Witch Doctor player can cast 
Voodoo Restoration to disrupt their last spell for Rubick to steal.
* 
Telekinesis can interrupt a channeling Death Ward. With Death Ward's high burst damage, combining Death Ward and Telekinesis to hold enemy in place can result in a solo kill in the early game.
* 
Paralyzing Cask provides an additional disable. The ability also helps moderately with farming.
* Voodoo Restoration provides some utility by healing Rubick and his team.
* Maledict is a damage-over-time nuke that amplifies the damage enemy taken.
* Telekinesis can reposition the enemy within the range of Maledict.
Additional:
* Rubick can steal Death Ward easily as it is a channeled ability and then use it to turn teamfight to his advantage.
* However, a skilled Witch Doctor will toggle Voodoo Restoration immediately after placing his Death Ward to prevent that.
Witch Doctor
* Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from Maledict.
Witch Doctor
* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
Witch Doctor
* Morphling can 
Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* 
Adaptive Strike (Strength) can interrupt Death Ward at a decent range.
Witch Doctor
* 
Arc Warden's 
Magnetic Field dodges all damage from Death Ward.
Witch Doctor
* Stone Form can easily interrupt heroes with long channeling spells, like Crystal Maiden, Bane, Witch Doctor, or Enigma.
Witch Doctor
* Heroes with plenty of summons, such as 
Broodmother or 
Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
Witch Doctor
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, 
Sniper, 
Ursa, Witch Doctor, etc.
Witch Doctor
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.
Witch Doctor
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: 
Disruptor, 
Death Prophet, Enigma, 
Faceless Void, 
Invoker, 
Lich, 
Magnus, 
Mars, 
Medusa, 
Outworld Destroyer, 
Phoenix, 
Puck, 
Queen of Pain, 
Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, Witch Doctor, 
Zeus.
Witch Doctor
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.
Additional:
* 
Light Strike Array cancels out Death Ward from a long distance.
Witch Doctor
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Witch Doctor
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Witch Doctor
* Heroes with long channeling abilities like Witch Doctor are easy targets for Kunkka to interrupt in team fights.
Additional:
* 
Torrent can cancel Death Ward from a far distance.
Witch Doctor
* Death Ward's first target (before it bounces) can evade it, therefore 
Windranger and 
Phantom Assassin are poor choices to use it on.
Witch Doctor
* Heroes like 
Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Witch Doctor
* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.
Witch Doctor
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, Witch Doctor, Enigma, Bane.
Additional:
* 
Meat Hook interrupts Death Ward from a decent range, even through Black King Bar & Glimmer Cape.
* Pudge can survive the damage from Maledict because of his 
Flesh Heap stacks.
* However the damage-over-time from 
Rot is counteracted by Voodoo Restoration.
Witch Doctor
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and 
Omniknight should play very cautiously alone...
Witch Doctor
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, 
Warlock or Shadow Fiend.
Dawnbreaker
* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,
Venomancer etc.
Dawnbreaker
* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,Venomancer etc.
Witch Doctor
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Witch Doctor
* Low health spellcasters: 
Lina, Witch Doctor, 
Tinker, 
Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Witch Doctor
* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.
Witch Doctor
* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor
Witch Doctor
* Heroes with the ability to heal allies will not be able to heal heroes affected by 
Doom: 
Chen, 
Dazzle, 
Io, 
Oracle, Omniknight, Witch Doctor, Winter Wyvern, 
Abaddon, etc.
Witch Doctor
* Paralyzing Cask will repetively bounce between Chen and his converted creeps every single time. This can get even worse if Witch Doctor buys Aghanim's Scepter that will allow his Death Ward to bounce between Chen and his converted creeps.
* Paralyzing Cask, Maledict and Death Ward combination will often kill Chen's allies before he can save them with 
Hand of God. And to make things worse, Chen has no way to cancel Death Ward on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* 
Voodoo Switcheroo from 
Aghanim's Shard cannot be interrupted by Chen's creeps at all because Witch Doctor is hidden for it's duration.

Dawnbreaker
* Starbreaker can deal huge damage to Chen and clear waves of his creeps.
* 
Celestial Hammer can deal damage over time to both, Chen and his creeps, which may force Chen to use Hand of God prematurely.
* Solar Guardian allows Dawnbreaker to counter Chen's pushing attempts and to rejoin her team with Solar Guardian when they require it. Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion while Dawnbreaker is airborne for it's duration, wasting much of 
Penitence's power.

Witch Doctor
* Paralyzing Cask can save ally from Legion Commander Duel's until she purchases Aghanim's Scepter.
* Voodoo Restoration can heal Witch Doctor allies from Duel's.
* Death Ward can help Witch Doctor allies from winning Duel's, if, he is not a target.
Dawnbreaker
* Solar Guardian can save allies who are being dueled and will interrupt her 
Duel initiation.
Witch Doctor
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: 
Spirit Breaker, 
Bloodseeker, Witch Doctor.
Dawnbreaker
* Dawnbreaker can easily clear waves of Naga Siren's illusions from 
Mirror Image with Starbreaker, Celestial Hammer and Solar Guardian.
* Aghanim's Shard upgraded Starbreaker will allow Dawnbreaker to dispel 
Ensnare and freely attack Naga Siren during 
Song of the Siren when combined with Black King Bar, a common item on Dawnbreaker.
* Solar Guardian allows Dawnbreaker to counter any attempts of Naga Siren and rejoin her team with Solar Guardian when they require it. Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion while Dawnbreaker is airborne for it's duration, as Naga Siren mainly relies on direct attacks in order to deal damage.

Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion while Dawnbreaker is airborne for it's duration, as Naga Siren mainly relies on direct attacks in order to deal damage. Solar Guardian can also be used after Naga Siren uses Song of the Siren near her allies to either escape from or counter-initiate against them.
Witch Doctor
* Paralyzing cask bounces between him and his wolves, keeping him stunned for long amounts of time.
Dawnbreaker
* Heroes with summoned units don't fare well against Dawnbreaker. (
Phantom Lancer ,
Beastmaster ,
Lycan).
Witch Doctor
* Heroes with magical or pure damage output will not have any problems against Atrophy Aura at all: 
Luna, Lina, 
Jakiro, Pugna, Bane, 
Snapfire, 
Muerta, 
Nyx Assassin, Enigma, Tinker, Witch Doctor, Zeus, Crystal Maiden.

Dawnbreaker
* Dawnbreaker can use Solar Guardian to help her team against Muerta whenever they are in distress against her, especially when trapped in the radius of the The Calling. Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion against Muerta's attacks from 
Gunslinger while Dawnbreaker is airborne for it's duration.
* Solar Guardian and Starbreaker can disable Muerta even through both, 
Pierce the Veil and Black King Bar, though Starbreaker will not deal any damage to Muerta as it's damage output is physical instead of magical.
* Celestial Hammer and Solar Guardian deal magical damage which allows Dawnbreaker to fightback against Muerta whenever she has Pierce the Veil. Dawnbreaker can also buy 
Revenant's Brooch to attack Muerta through Pierce the Veil with Starbreaker.
* Dawnbreaker is also common Black King Bar wielder which allows her to protect herself against Muerta's abilities. Aghanim's Shard upgraded Starbreaker can also give Dawnbreaker debuff immunity against Muerta's abilities.
Dawnbreaker
* Solar Guardian can save allies caught inside Arena of Blood.
Dawnbreaker
* Spectre has no innate disables or silence to stop any of Dawnbreaker's abilities
* Solar Guardian allows Dawnbreaker to quickly stand next to one of her allies, denying Spectre any of 
Desolate's bonus.
* Luminosity outheals the damage dealt by 
Dispersion.
Additional:
* Spectre has no innate disables or silence to stop any of Dawnbreaker's abilities
* Solar Guardian allows Dawnbreaker to quickly stand next to one of her allies, denying Spectre any of Desolate's bonus
* Luminosity outheals the damage dealt by Dispersion
Witch Doctor
* Maledict cannot be dispelled by Phantasm, and can be used to tag the real Chaos Knight hiding within his illusions.
* If Witch Doctor has an Aghanim's Scepter, Death Ward will bounce between Chaos Knight's illusions, destroying them quickly.
* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys Glimmer Cape or Black King Bar.
Dawnbreaker
* Solar Guardian can save an ally getting targeted and focused by Spirit Breaker.
Witch Doctor
* Death Ward with Aghanim's Scepter makes quick work of the spawned illusions from Disruption.
* However, it can be cancelled by Disruption until Witch Doctor buys 
Linken's Sphere or Black King Bar.
* All of Witch Doctor's abilities are active, making Demonic Purge break from Aghanim's Scepter useless.
* Voodoo Restoration can out-heal the damage from Shadow Demon's abilities.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Maledict or Paralyzing Cask for the enemy.
Witch Doctor
* Voodoo Restoration heals to counter Bloodseeker's 
Thirst.
* 
Rupture is generally useless against Witch Doctor while he is staying on Death Ward.
* Although Witch Doctor needs to be careful as Blood Rite can interrupt Death Ward.
Dawnbreaker
* Heroes with summoned units don't fare well against Dawnbreaker. (Phantom Lancer ,Beastmaster ,Lycan).
Dawnbreaker

Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, Phoenix, Razor, 
Huskar, Batrider, 
Kunkka, 
Tidehunter, 
Wraith King, Sand King, Medusa, Dawnbreaker.
Witch Doctor
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, 
Silencer, Shadow Shaman, Grimstroke, Witch Doctor, 
Riki, Faceless Void, 
Skywrath Mage, Puck.
Witch Doctor
* Heroes with channeling abilities: Enigma, Witch Doctor, Crystal Maiden.
Dawnbreaker
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: Bane, Enigma, Pudge, Shadow Shaman, Dawnbreaker, Warlock, Crystal Maiden.
Dawnbreaker
* Heroes whose abilities can affect multiple enemies at once: Dawnbreaker, Ember Spirit, Lina, Luna, Jakiro, 
Leshrac, Invoker, Muerta, Dazzle.
Dawnbreaker
* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.
Dawnbreaker
* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,Venomancer etc.
Witch Doctor
* Voodoo Restoration heals to counter damage over time of Poison Nova and 
Poison Sting.
Witch Doctor
* Heroes with plenty of summons, such as Broodmother or Nature's Prophet can have their minions soak up most of your Paralyzing Cask.
Dawnbreaker
* Starbreaker and Celestial Hammer does high AoE damage which easily clears {U:Treant}, shutting down most of Nature's Prophets damage and pushing power.
* Dawnbreaker can teleport to deal with split-pushing Nature's Prophet and rejoin her team with Solar Guardian when they require it.
* Since Starbreaker clears trees in its path followed by a stun at the end Nature's Prophet will be unable to escape the dangerous situation by using 
Sprout on himself and teleporting away with either 
Teleportation or 
Town Portal Scroll.

Witch Doctor
* Witch Doctor's Maledict burst damage can be prevented by Sunder if timed correctly. But it can kill Terrorblade if he has no target to be Sundered with, especially in the early game.
* Death Ward deals physical damage, and Terrorblade's high armor can help him survive against Death Ward. However, Terrorblade has no disable in his skillset at all, and he cannot stop Witch Doctor from channeling Death Ward to maximum. And if Witch Doctor owns Aghanim's Scepter, attacks from Death Ward will be able to bounce around and wipe out Terrorblade's illusions and his team.
* Terrorblade must be careful as Paralyzing Cask is commonly tricky to dodge for him due to his reliance on illusions.
Witch Doctor
* Heroes who have channeling abilities because Terrorblade has no disables to cancel them at all besides 
Terror Wave from Aghanim's Scepter, and he does not like buying disabling items at all: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.

Dawnbreaker
* 
Spiked Carapace can stop Dawnbreaker's Solar Guardian which will eliminate her global presence and limits her movement around the map.
Additional:
* Spiked Carapace interrupts Starbreaker before Dawnbreaker has her Aghanim's Shard, as well as Solar Guardian during the initial channel, making her ineffective at joining and dealing damage in teamfights.
* The slow projectile and damage over time effect of Celestial Hammer makes it easy to stun Dawnbreaker if she attemps to engage or chase.
Witch Doctor
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: Axe, Broodmother, Dawnbreaker, Enigma, Huskar, Jakiro, 
Legion Commander, Lina, Luna, Lycan, 
Slardar, Slark, 
Troll Warlord, Witch Doctor.
Dawnbreaker
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, 
Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, 
Doom, Dawnbreaker. However, this also means they are easily stunned.
Witch Doctor
* Paralyzing Cask's short stun rarely prevents Monkey King from ambushing Witch Doctor.
* Death Ward's long channel is easily interrupted by Boundless Strike.
Witch Doctor
* Another hero that should not leave a special circle for his ultimate. The only thing to be afraid is 
Boundless Strike.
Witch Doctor
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor
Witch Doctor
* Multiple attackers thanks to summoned units or clones: 
Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, 
Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Witch Doctor
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Dawnbreaker
* Heroes capable of perofrming interceptions who can anticipate and counter-initiate after Phantom Assassin blinks on them with Phantom Strike will often kill her than the other way around: Axe, Bane, Dawnbreaker, 
Centaur Warrunner, Luna, Medusa, Omniknight, Pudge, Razor, 
Terrorblade, Underlord.
Dawnbreaker
* 
Nethertoxin disables Dawnbreaker's 
Luminosity. Since she's a melee hero, she needs to close gap to attack and Nethertoxin will be bad for her since she cannot heal.
* 
Viper Strike and 
Poison Attack will severely slow her down and combined with Nethertoxin, it will be her death sentence (unless her Celestial Hammer or Solar Guardian are off cooldown). Besides that, chasing her down will be easy due to the slow.
Witch Doctor
* Voodoo Restoration heals to counter damage over time of Viper abilities.
* Viper has no way to cancel Death Ward, even through 
Rod of Atos.
Dawnbreaker
* Savage Roar interrupts Starbreaker.
* Dawnbreaker is a slow moving hero. Although tanky, Lone Druid can eventually wear her down with his better movement speed.
Witch Doctor
* Paralyzing Cask is likely to bounce between him and his bear every single time.
* Lone Druid's lack of mobility makes him vulnerable to Death Ward and Maledict.
Witch Doctor
*
Death Ward can be easily canceled by Jakiro, or even turned against him with Macropyre, due to it's attack range being smaller then Jakiro's cast range. And 
Crystal Maiden, his Scepter does not allow him to move while using it. 
Voodoo Switcheroo is even easier to land Jakiro's Macropyro/Ice Path combo. And unlike 
Crystal Maiden, Witch Doctor's Aghanim's Scepter upgraded Death Ward does not allow him to move while using it.
Maledict can be quite effective on Jakiro, along with repetitive stuns from Paralyzing Cask, it is very difficult to get a strong Maledict on him. Although Witch Doctor's Paralizying Cask, Maledict and Death Ward combo will still quickly eliminate Jakiro.
Voodoo Restoration will partly protect his allies from Jakiro spells, as it heals based on their Max Health once he gets his Talent (Level 25). Before then though, it won't make a dent in the damage Jakiro deals.
* While
* On the other hand.
Dawnbreaker
* Heroes with channeling spells are very easy targets for Jakiro's abilities:
Crystal Maiden, 
Dawnbreaker, 
Enigma, 
Pudge, 
Shadow Fiend, 
Shadow Shaman, 
Warlock.
