With tank damage scaling off VIT, there is no longer any excuse for a tank doing poor DPS. HP vs DPS is no longer an argument. You have both. Get to work.
With tanks having so much extra HP now, there is no longer any excuse for a healer not to contribute significant DPS. Tank has 30k HP. Don't just stand there. Get to work.

Pretty much strengthens the idea that we are all DPS, just tanks and healers have extra responsibilities.
