Fury and Arms are both solid in solo content and can deal out a lot of damage with their various abilities.They both also have plenty of sustain to get through their enemies without having to slow down.

Which Warrior spec is best for DPS?

For Classic end-game content, Fury is the best spec for DPS Warriors. They will either use a slow 2H weapon with a Slam build or use two 1H weapons with high DPS as Dual-Wield Fury. For PvP, DPS Warriors will use a slow 2H weapon for an Arms Mortal Strike build.

Is Fury or Arms better for leveling?

Play Fury or Arms for leveling: There are only two specs for leveling, and both use two-handed weapons for damage. While leveling, I recommend playing as Arms, as both damage dealt and taken are more consistent. I play Arms whenever I level due to an extra layer of danger that Fury adds to the equation.
