Serious question. I can't think of a single powerful gay lore character, during TBC beta they took away all the gay jokes from blood elves and like quadrupled their musculature, and now they replaced Theralion's voice with a generic dragon voice.
I don't know about anybody else but I would love to see a gay faction leader or something. Not only would it send a message of tolerance but it could potentially draw in new players. My best friend, for one, said he would join then.
