“In some ways,” Chilton says, “I wish we had kept some features bound to the expansions they lived in to make room for more innovation without players feeling like we were taking something away.” He points to the Archaeology profession introduced in Cataclysm as an example; he wishes they’d removed it in time for Mists of Pandaria. It’s a practice he intends to follow in the future. The garrisons introduced in the upcoming Warlords of Draenor expansion, for instance, won’t carry over to whatever comes next."
