Man I feel like my warriors were not properly handled... At this point in the game I only do 250pts max damage with one-handed + shield warrior, and 350pts max damage with two-hand expert warrior...
That does seem a bit low. The unbuffed damage range for my 2H warrior is 403-806 (227-455 from weapon) at L17. I get a 70% increase from 7 Tenebrium and an additional 15% increase from 4+ Leadership from my mage. I'm currently using a crafted L17 2H axe.
