We would probably have to disagree at this point.

If a tank is taking damage and not getting more dps out of it, then this is a mistake.

But I see no reason why you should not stay out of grit as long as possible unless

1. Healers are OOM or spend too many GCDs so they let other people die (this is a raid dps loss)
2. You are gonna get one shot
3. You can't do dps but will take damage (like boss disconnects + nukes)

If there a real desire for damage then a tank mitigating more damage and allowing a healer to even do something as simple as put their dots on a boss or AoE a group of mobs a few times is worth more damage overall than the tank dancing out of their tanking stance to do a little more damage. The dots on my astrologian while they are up can deal 300ish DPS while they are up which is worth more than 30% more damage for a duration on any tank class that is both taking damage and trying to deal it. In the end it is much better if the tank keeps their tanking stance on to mitigate damage than attempt to do a little more damage that a healer can easily make up for with just dots.

It's subjective to what your "job" is beyond

Tanks: keep enmity
Healers: keep all alive
DPS: kill crap

Outside of that, it's whatever helps increase party/raid-wide DPS. If a full turtle tank and a DPS-stance healer does that, so be it. If a DPS-stance tank and a HPS-focused healer does that, then it's all the same.
