I prefer a predictable cycle over change for the sake of change. WoW does change for the sake of change every xpac and it sucks having to relearn your class over and over again, sometimes hating what your class became due to the changes. I am happy with the stability of knowing what to expect with familiar systems that, while they might expand, essentially stay familiar. I don't need things to be "shaken up" and everything I know thrown out the window every xpac. What I need is a familiar system that isn't turned on its head every 2 years, a good story to follow, and stuff to do that's rewarding and entertaining.

Change for the sake of change is stupid IMO.
