Man playing a melee carry without CC looks so tough. Can only dish out damage if the Dark Seer or the Tiny hold them down long enough. Even fights with metamorphosis are difficult if everyone can monkey jump, cookie, leap, or blink away.
Theoretically TB should beat AM in 5v5 gank because AM's shadow gets lot stronger as AM farms. You should see how fast shadow runs and attacks after AM butterfly. Leaves him mana-less inside 5 men gank. Also there is no running away from it. Even if you blink, it comes to you without getting blocked and hits you no matter what. Taste of his own medicine.
