"You pull, you tank" is a bad mentality

[Jojoya]

Trust the healer has a better judgement than the tank over what the tank can handle, as it’s the healer’s primary role to keep that tank alive. Just because the tank is scared to take an extra hit doesn’t mean they are incapable of taking that damage. If you want to single pull, consider a different role.

That's a big risk when you don't know the healer and their experience.
