I've started leveling a warrior now, hes 15 at the moment with BoA shoulders, chest and the axe, i have a couple of questions.

For instance at leveling 40 i get MS as im leveling as arms, what attacks do i use for leveling? at the moment its just Heroic Strike with the odd overpower, at 40 do i use only MS and slam?

And in PvP i guess heroic strike is just a rage dump but what are the main attacks for dealing damage aside from bladestorm and MS? Is slam used in pvp at all?

thanks
