* 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)

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

* 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.

* 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.

* Ice Blast ignores Dragon Knight's armor and kills him prematurely.

* Arcane Orb's constant pure damage output is devastating to Dragon Knight.
* Dragon Knight's relatively low mana pool leads to heavy damage from Sanity's Eclipse, which also bypasses his armor.

* Fortune's End can easily dispel Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from Shadow Realm.

* Fate's Edict negates all her magic damage in case she catches a single hero.
* False Promise's strong dispel removes Dark Willow's disables.

* Counterspell negates Dark Willow's high magic burst damage. Its active blocks Cursed Crown.

* Rot and Meat Hook hits Dark Willow even when she uses Shadow Realm.
* Flesh Heap reduces Dark Willow's magic burst damage.

* Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, Life Break remains a constant threat due to the slow and percentage-based damage.

Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.

* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, Spectre and Dragon Knight can be disabled easily with Sharpshooter's break, reducing their potential in teamfights.

* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.

* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, Vengeful Spirit, Dark Willow.

* 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.
