When using Riposte and Missile Deflection trait, you can reflect projectiles for 4+ seconds when canceling the Riposte cast. I thought nothing of it for a few weeks, but it is indeed extremely overpowered.
I’ve reported my findings in game, as well as on the forums in the past. I believe this should be fixed as soon as possible.
While we’re at it. Canceling Riposte gives the ability Adrenaline Rush. Adrenaline Rush gives adrenaline when you cancel Riposte. It only gives 3% adrenaline. This might not be working as intended.
