There are multiple animation cancel exploits being used in the game currently.
The most notable are : Feral Rush, Leaping Strike, Berserk and Shield rush.
With a hatchet currently, someone can roll dodge into berserk, cancelling the initial root animation, and then attack animation cancel feral rush to basically fly like spider man across the map and kill you. Due to the haste from berserk it is impossible for most builds to escape.
Similar things can be done with leaping strike and shield rush by attack animation cancelling.
This exploit is causing these abilities to not function as intended and in some cases the ability moves almost twice the intended distance.
It has also been proven in multiple videos that these animation cancels can be macro’d into one button.
This is game breaking.
