I've played off and on for the past 6 or so years. Not playing at the moment, Cataclysm never really managed to keep my attention, just got to 85 in a couple days and stopped playing again. I've thought about resubscribing. Actually the biggest barrier is I just don't have enough HDD space at the moment, and I don't feel like deleting anything or buying a new one. Which I guess shows how much I actually feel like playing. I think if I had a better guild to go back to it would be different.
With that said, WoW is easily one of my favorite games of all time.
