"You pull, you tank" is a bad mentality

[loosie]

You do realize that if it's pointless if you don't even let tanks do their job, right?

Maybe you should define "not letting tanks do their job".
Because if you pull a mob to the tank and he stops hitting the AoE buttons, it's the tank who refuses to do their job.
And if you're not required to tank, why does it bother you so much that you're not tanking?
