I'm a 50 warrior trying to choose an endgame spec. I really enjoy PvE and I'm looking forward to raiding but I still want to be able to PvP and play on an Arena team. I've been specced for dw fury the whole way up to 50, but I'm strongly considering switching to an MS/imp slam build. I've read that while well-geared dw fury warriors can put out great DPS in raid situations, they don't have much viability in PvP or Arenas because they lack burst damage. I've also read that with a good imp slam rotation (autoattack - slam - MS - autoattack - slam - WW), a warrior with a 2h can put up solid DPS in raids while getting to spec MS for PvP. My question then, is how does a warrior with a 2h slam rotation compare with dw fury for PvE DPS?
I don't mean for this to be a "rate my spec!" post, but I'm going to include it anyway.
