Wyn: interesting trivia: if you read the lore, the horde are the "good guys," if anyone is
Orc & Tauren easily.
Trolls...hmm they are such a sidekick race its hard to tell... certainly they've stopped some bad evils(hakkar and the Aqir)...but they also started some(hakkar and other crappy voodoo). Neutral like any good mercs.
Undead... solid resistance fighters/good guys in my books. Sure they want more people to be undead but thats practically a biological directive to reproduce. I mark them as 75% good.
Blood Elves.... Misguided but good at heart. The moody teens gangsters of WoW. And now that Sunwell has happened they are on the path to redemption.
