"You pull, you tank" is a bad mentality

[Tanis_Ebonhart]

What if I’m the healer, pulling, because I’m experienced and know how much punishment I can let the tank take?

Tank needs to do their job and not have a hissy fit

And how does the Tank know this? And how do you know the Tank knows how to keep up and cycle mitigation? Especially if they now have multiple more packs pulled in than what they weren't expecting?

A good healer isn't selfish. They consider the rest of the group too. You should try that some time.

Not to mention that overpulling really only exists in aar and hw content as stormblood and up have a lot more stop. You know, all the content where Tanks have far less resources at their disposal?
