DPS
For raid dps I really reccomend going Duel Wield Furry. It's going to be the best for overall dps and if you want to compete with other classes (or you're wanting to see someone other than Phame at the top of the list) this will be the way to go.This site explains fury fairly well and here is the reccomended build for fury warriors.
