We have Blood Elves, aren't they gay enought? ( ͡° ͜ʖ ͡°)
But totally serious: no, we don't need LGBT representation. There is no reason of that. And I really don't like when political or controversial ideas are implemented into popculture. Blizzard is popular enough so they don't need to reach for such cheap ways like Doctor Who lastely does.
That's for sure not true, maybe depending of environment. Generally it's hardly over 1%. But that's not a big deal.
What about disabled people? Why can't my character be in a wheelchair? Are Blizzard ableist?!
What about fat people? Why can't my character be fat? Do Blizzard hate fat people?!
