In all fairness, Blizzard brought it on themselves.
No, not being nasty. But have you seen the dance that worgen women do? It's Poker Face.
So much groping. Why is there so much groping?
It's not that I mind, but it's definitely the perviest dance in the game. So saying that pervert is reserved for the worgens actually has some kind of solidity in lore. Not to mention that it's based upon Gregorian/Victorian England, and the heels of that era pretty much exemplified deviance.
THAT SAID. The Gilneans are pretty much the only interest I have in WoW.
Possibly for that reason? Though probably not.
The female Night Elves use the dance from Alizée's J'en ai Marre dance, which is so jailbait-y that Pedro Behr gets a little excited.
