I think people on the forums gravely misunderstand that what they do does not apply to 99% of dungeon runs. Most people do dungeons in DF. You can't matchmake with 1 tank and 3 DPS. So the scenario in question means the healer does absolutely nothing while the tank and 2 DPS are doing it without them.

And just because something can be done, doesn't mean that the people saying it or thinking they can do it are capable of it. So many tanks are too afraid to even use their invuln because they think it's for emergencies only. I seriously doubt it's as common as you think.
