Talking about Monk here, there needs to be some animation updates, True Strike and Snap Punch are probably the 2 that need it most. Things like Dolphin Blow or adding more kicking animations. Something like a Somersault animation would have been good, but they put it into Celestial Revolution, which you never see.

Onto MCH, the only animation I really think needs an update is Gauss Round, it just gets lost. I'm thinking maybe something along the lines of much more recoil on the character and an animation that indicates a high speed projectile. I'm thinking a bright blue beam of light with circles that pop out of it, almost like a sonic boom effect.

From the DPS I play often, that is all I have, mainly taking the more boring animations and breathing new life into them.
