That's not a warrior, that's a warrior/mage hybrid.
The point - for me - is comparing a pure mage to a pure warrior.
My pure warrior did more single-target damage than my pure mage, but had FAR LESS usefulness in every other situation.
Also I am pretty sure your numbers are off. Even at level 21, my 2-handed warrior's attack damage was only 300-600 (in the inventory screen). They frequently did more damage, thanks to Bully, Enrage, Oath, and crits, but they also frequently did less damage. And when they DID deal tons of damage, it was usually thanks to my mages buffing them and weakening the enemies.
