I think they skewed it to be TOO simple. We need some of our signature moves back (carnal chill, testudo, etc). I mostly played tank at that time so those are the ones I remember, but having those seemed to make every battle unique and a lot more engaging than just button-mashing.

I don't know why, but I expect in 5.0 we'll finally see some PVP changes.. or maybe pvp will go the way of Diadem, which I sincerely hope it doesn't
