(Orcs / Goblins need to be on the list ._.)
Humans. I've been called boring for liking humans in any Fantasy setting (Be it WoW, Warhammer, LotR, etc.)
I like them because they're easier to identify with, they often have their backs against a corner (I.e, they're usually the race who happens to be in a "We're so f***ed" position), and in fantasy I can forgive them for having humanity's flaws, since the opponents they face would scare any real person to death, and it's then understandable they might go insane and slay their neighbour or whatever.
And they -tend- to have the most awesome armour, such as this from Warhammer Online: http://mythicmktg.fileburst.com/war/us/home/images/armiesofWAR/empire/KnightoftheBlazingSun/kotbs-concept-01.jpg
(Fuck you, plumed helmets are awesome, no matter how impractical it is!)
I also have a friend who loves Dwarfs to the point of it bordering to the erotic, so I'm not that fond of them, for instance.. >_>
