DPS Stance vs Tank Stance Including Healer DPS

[Reynhart]

The take no damage/deal no damage style is not really all that fun.

The core of the problem. Not all tank think that way.
Having the strategic options to go full tank stance and let healers have far more room to DPS, or going full DPS stance while healer are more focused on keeping us alive would please both types of tank and healer players, instead of forcing everyone into a single meta.

I'm practically on the brink of death when playing out of tank stance; one miss timed heal, one crit auto away from certain death

Problem is, that situation is mostly on the healer's shoulders, not yours. So you're thrilled at putting pressure on someone else.
