Hey, i have a friend who is approching level 80 on his first character, a warrior. Having never played one, i don't knbow much about it, so i thought i would look around the forums. He is sporting the 54/17/0 arms dps spec; http://ptr.wowhead.com/?talent=LhrhbfIt00bRdGuioGx00xb but one thing i couldn't find, is what stance to be in. looking at what some people said the rotation was, he must have to be in battle stance, but that cuts out alot of ablilties such as pummel and whirlwind. so my question is, should he be in battle stance or beserker. also, any other tips on anything else he should know would be appreciated
