On Dark Knight after some practice I average between 890-900 on a dummy with party/food/pot (No Storm's Eye though) and on Paladin with same conditions I get 840. These are both with currently maxed gear and full strength accessories. However, the Dark Knight hits 0 TP at about 2:10-2:15 and Paladin at about 2:30-2:35, and Warrior can pass both of these job's DPS as off tank (and main tank) while sustaining for much longer. So, while Dark Knight may be able to "nearly" match a Warrior's DPS it is not a very reasonable comparison in most fights when quickly TP starved.
