I'll admit to being embarrassed here. This thread was my idea, and I never came back to post in it!
- Goblins. Something appeals to me about the idea of an anarcho-capitalist society in which people routinely do things they themselves consider immoral. Honorable mentions go to the Arrakoa for being weird, and the Sporelings for their biology. Also Tuskarr for bizarre mental suppression.
- I can't say anything was "least interesting." You could put a steaming pile of crap in front of me and I'd examine it with rapt fascination. (hyperbole)
- Humans--specifically, Dalaran. I wish more people would be open-minded and judge everyone on their merits. Besides, a university setting is what I've became accustomed to. Come think of it, that sounds more like Gnomes...
- Draenei, hands down; but that was kind of the idea. They are alien, and kinda scary if you stop and think. Your conception is the prime influence on my headcanon.
