For Perfection there's just one move that I never see use for... His ground blink.
What this move should do is teleport you a few feet by holding a direction before you use this move, making it much more controllable, and getting rid of the need to have the opponent close
As a bonus, maybe it can even force the enemy to hesitate if you teleport right in their range, their style abilities put on a half second cooldown, so you can't IMMEDIATELY be stunned
Mouse aim sucks... and this is such a simple change honestly
