With Torment of the Banished and Hailstorm, 15/51/5, i'm seeing around 2100dps, 25 man buffed, using all cooldowns and using a 2s/5r rotation.
With Titansteel Shanker and Rolfsen's Ripper, 51/13/7, i'm seeing around 2600 dps with the same buffs.
Does combat suck so much that I lose 500 dps even with WAY better weapons than mutilate?
