Not to sound totally racist but IMO Gnomes look just damn creepy and rediculous atop a dreadsteed. They are the worst looking characters in the game.

If all you care about is the stats then I would say that Gnome wins hands down. Escape artist and improved intelligence can really benfit a warlock.

I know what your going to say, your appearance doesn't really count for sh*t in WoW and thats absolutly true but personally I just can't get over rolling a gnome character.
