i generally don't care if i MT or not (should be mentality of all tanks)
i just ask in 8 man situation
in 4 man? i don't have much of a choice
9 times outta i 10 when i try to MT in 24 man have someone just spam there aggro combo and use Provoke/Ultimatrix when they can "no i must be the hero that tanks the boss" mentality
really just ask don't let this game suffer even more with lack of communication.
