So I am an arms warrior currently just about to hit 85 , I know this may sound noobish but I mainly stick in Berserker stance even in PvP, I feel like I am doing way more damage that way, someone mentioned that if I want to do it like that then I should re spec to a fury warrior, is this correct? would I deal more damage as a fury warrior only staying in Berserker Stance, and please know what you are talking about when you answer this hehe!

You're going to do more damage in Berserker stance regardless of your spec. If you mainly do PVP, Arms has better talents than Fury. Stick with a spec designed for PVP, but use whatever stance you want.
