Trolls make decent DW fury warriors imo. Orc stun resist isn't reliable, I have seen enough orcs being completely stun-locked 9/10 of the times by rogues. UD is better than orc/troll just for WOTF, godly for pvping against locks/priests, and in dragon fights because horde doesn't have fear ward and tremor totems are totally unreliable.

I think NE rogues are better overall too lol. But human rogues have the advantage in rogue vs rogue, since it is all about who gets the opener.
