And complaining about gimmic fights (granted we had a lot more of them this tier than last) is same as complaining about dps on gimmick fight.
I mean in most fights i can see tanks doing ~ dps to an equally skilled and gear dps.
Because depending on the fight you can generally find a benefit from switching out a healer for a dps, or a dps for a healers, or a dps for a tank (dark animus comes to mind).Why not? Scenario 1: Tank has 16 adds. Scenario 2: Tank 1 has 8 adds, Tank 2 has 8 adds. Reasonably you'd imagine less total damage goes out from Scenario 2, not even less damage per tank. Handling 8 adds is a lot easier than handling 16.
But w/o the "higher than normal" veng there's going to be 0 benefit from switching out a tank (outside of slightly more dps)
