* Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.

* Dragon Knight has no built in disengage from Frost Arrows, and Marksmanship procs ignore base armor, bypassing Dragon Knight’s tankiness for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With Aghanim's Shard, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an Eye of Skadi)

* Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.

* Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.

* Static Link saps Dragon Knight of his already low base damage, making him even more useless in a fight if he gets kited.
* Storm Surge makes Razor much faster than Dragon Knight, and hard to catch.

* Arcane Orb's constant pure damage output is devastating to Dragon Knight.

* Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with Waning Rift.

* Cold Feet and Ice Vortex both hinder Dragon Knight's movement greatly during teamfights.
* Ice Blast ignores Dragon Knight's armor and kills him prematurely.

* Fury swipes can tear Dragon knight down as it stacks infinitely.

* Fortune's End can easily dispel Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.

* Dark Willow's chained magic burst requires a lot of mana, setting her up for damaging Mana Voids.

* In the early game, a Dragon Knight without Black King Bar is basically defenseless against Viper.
Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.

* Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.

* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King

* Elder Titan's Natural Order completely nullifies Dragon Knight's high armor.

* Heroes who can silence will shut down Dark Willow entirely: Death Prophet, Silencer, Drow Ranger

* Durable heros relied a lot on their main passive effects and items' effects such as Bristleback, Underlord and Dragon Knight can be removed their effects easily with Sharpshooter's break.

* Slardar can chase Dragon Knight down with Guardian Sprint and stun him with both Slithereen Crush and his passive Bash of the Deep. He can also use Corrosive Haze to whittle Dragon Knight's armor.

* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.

* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her. Additionally, it dispels Cursed Crown and Bramble Maze.

* However, if Shadow Realm is activated during Omnislash, then the attack damage is negated (though Omnislash can still jump to other enemies).
