My only problem with the looks of combat is that the animation can sometimes end before the Global Cooldown is up, making it appear as though character is standing around doing nothing for a half second here and there between combat moves. That's what makes it look not as fluid as WoW players are used to - each move itself looks fine, but move to move to move can look choppy.
Shouldn't be too hard for them to fix, just have to slow down the timer on the animation. I'll post it on the beta forums.
