Cataclysm is beautiful, but it ultimately brought home to me how much I hate WoW's combat architecture, and how I disagree with almost all of Blizzard's game design choices. And so, in what was probably a foregone conclusion in the first place, I've cancelled my subscription again.
That being said - Cataclysm is truly polished work. If this had been the first expansion I'd played, rather than the Burning Crusade, I might never have left.
But now, it's time to catch up with Gwen and Keiran, and to get back to feeding toes to Rotty!
