The more damage a main tank takes, the more healing he must receive in order to survive. In a raid setting, if a healer spends more time healing the main tank, the less time he can spend DPSing. As such, I'm guessing there's a tradeoff between tank and healer damage, where increased damage on the tank's end corresponds to a decrease in damage on the healer's end.

My question is this: What do you guys find to be the best way to maximize healer + tank dps? Do the healers and tanks both deal more combined damage when the main tank is tanky (always has tank stance up), or do they deal more combined damage when the main tank is maximizing his dps output by foregoing tank stance?

Of course the situation is more complex than I make it to be; for instance, the class of the main tank will have a major impact on the combined dps when considering the dps dealt in or out of tank stance. This is just a thread that encourages discussion on what you have personally found to be most effective in maximizing healer + tank damage while maintaining the balance needed to keep the main tank alive.
