I wish WoW had the same skill system like Diablo 3. Just 6 slots with a primary and secondary attack, some utility/offensive CDs and a few passive ability slots. Why? Because I find myself staring at my action bars 90% of the time I'm in a raid encounter, timing endless rotation patterns. Why is this considered to be fun at all? "Hey look, the boss throws 6 different attacks at you while you press 1121131121134441112314 and move out of the fire... great. :-/
I rather have a minimalistic set of skills and more fun with what is actually going on in a fight.
