My vote is for orc's their racial is like another trinket. BUT a buddy of mine just started boxing and went troll. Blizzard added alot of +haste gear with the SSO content. This could be the "new" stat that blizzard is wanting people to go towards. Which is better 10% haste for 15secs or a ~140 spell damage? I don't think anyone can tell you that right now.

I saw someone was running 1 Tauren and 3 orc's. That was kinda cool for pvp. As the orc's could kinda hide int he taurens body.
