Dps war is as easy as turning off Defiance. My current set up (str20/vit10) allows me to reach the 10k+ hp with Defiance + ToB + party bonus w/o food. Also if i get a melee I get the str bonus putting my str at 400. As soon as I get my last ilvl 90 ring I'll go full Str. I'm noticing a 50 point damage (str20) difference when off Defiance. It allows me to effectively be the OT without being to squishy. IMO as long as your hp can hit above 10k with buffs then you have more than enough into vit.
