IMO for PvP, if you are going for an MS build, go 2h axe specced for the extra +crit, or you could go 2H Mace with the mace spec for the stun proc. I think it's a matter of preference. I have asked before about spec-ing, and for the most part the general concensus is that DW is for DPS/raiding, 2H for PvP. For leveling, I don't really think DW/2H matters, because they are both drasticaly faster leveling than Prot. Hope this helps.
