Is WotLK needed in World of Warcraft for Cataclysm to work
Yes. As with all previous expansions, you must have the expansion before in order to upgrade to the current expansion. IE: you need Vanilla WoW, Burning Crusade, and Wrath of the Lich King on your account in order for you to upgrade to Cataclysm.
