Side note: Tanks would feel more confident to pull if they weren't seeing their health drop to less than 20% with a grudging Regen being tossed their way, so the healer can fling a few more rocks.

FFXIV has a big dissonance problem with its role culture, where tanks are almost the only ones expected to adhere to their role.

Red DPS get to pull so the tank will die, because the Green DPS doesn't think their primary job is to heal, and despite what we might wish in perfect fantasy world, the Blue DPS isnt invincible.
