Nostalrius Begins - Quality wow vanilla realm (1.12)

I don't know which weapons to use or which spec I should take.

Sorry if this post is n00b, but I've never level'd a warrior before.

Hey man, fellow warrior here. dual wield is weak as hell due to missing until thrash blade, and even then it's not better than 2handed fury or arms b4 being 60 with decent gear/hit chance. I personally recommend 2h fury over 2h arms for leveling, but some people say that at 40 to go arms for mortal strike, then fury again at 60 for pve. if you plan on doing pvp while you level up, then definitely arms at 40 for mortal strike. warriors are rough to level but stick with it, we are very gear dependent and excel later on!
