Evade’s purpose is to be preemptive but I think allowing us to expend an evade charge to free ourselves of an unlucky stun would help with the over-oppressing amount of cc in the game. Perhaps as a consequence you cant evade for a 10 second window or make it so it cant be used to break a stun with evade for 30 seconds or something.
Kinda more like a get out of jail free card that cant be heavily relied on but used during nasty chains of cc.
