As dps sorc I didn't have any problems. Too much flashiness tho. Only apply animation to the ability being used and on cooldown. Also, add some sort of numerical timer so we can tell easily at a glance how much time is left before the ability is ready again.
Also, please make our own rebuffs on targets bigger so we can tell when they are running out so we can reapply them. Hard to know who's debuffs are whose with 4 sorcs in a raid.
