I only let them die, or get close to dying if they purposely pull mobs. I understand accidental pulls. It happens.

It's natural some DPS will gain alot of aggro with their rotations, I view it as a challenge and adjust accordingly. But I'm a stance dancer tank. I will start in tank stance then switch to offensive. I know when to switch back and forth if needed.

But you go an pull a mob that I didn't, it's all yours buddy. But as a previous previous said, that was the general rule when bards were running around pulling all the things. It doesn't happen as much anymore thankfully.
