So you leave the game due to how its fundamentally designed, come back, and expect all of that to have changed? Um....ok.

And if you think letting players adjust the speed of combat in an MMO is a good idea, well i dont quite know what to say other than "game balance in an MMO".

I find the pace of combat to be perfectly acceptable at end game as it is. In raids, its leads to more strategic thinking, planning and execution. But this is just a personal opinion.
