The dialog isn't tailor made for you. The mantids keep telling me about how "many of my lifetimes ago, bla bla bla". I'm a draenei, near as I can tell we don't have a shelf life.
Then there's all the NPCs that put their arm around me and call me "young", when I could be older than oh, I don't know. Human civilization.
All of the quests assume you're human, unless it's an horde quest, in which case they assume you're an orc. I hate it.
It makes no sense at all for the alliance to call me a savage. Seriously, blood elves may be many things, but not savages, quite the opposite. It's obviously directed towards orcs, and the quest assumes you're an orc.
