Don't sell your WoW account. I sold mine right at the end of Burning Crusade and still came back in Wrath. Then quit at the end of that and played when Cataclysm first came out. Then quit that and now I'm subbed again. I played Warhammer for a while last year, but there's not enough staff-power to make that game near what it could have and should have been. Keep your battle.net account. Wow always changes, sometimes for the better, sometimes for the worse, but usally both.
