You're an ignorant fool. Blizzard had plenty of time to squeeze out this minor feature, that was for all intents and purposes promised, BEFORE Cataclysm went into full production. Blizzard is a massive software company, they arn't working with 20 people either, moron. They seemed to be able to divert or hire a few people to make that money-grubbing pet store, they should have been able to pull off at least a simple rescale of other races skeletons and fix a few skeleton rip problems so other dances could be available to other races. You whine and complain that they are producing cataclysm but they are fumbling the ball on that too for how many problems people claim are on the PTR and how long it took them to set a late release date. Blizzard failed to "keep me engaged" when I canceled my account months ago because of how stale and boring their game was waiting for cataclysm (after ICC they pissed out little nothings to keep fools paying while they string them along)
Stop defending a company that doesn't want or need your little fanboy back-up, there's no way a simple "dance studio" could be so hard that it has been in production so long that a complete expansion would come out before it. Stop cowering behind blizzards inept excuses while worshiping them and grow a pair and call them out on doing a terrible job on at least something.
