Short Answer will always be no.Long Answer: One: nobody ever knows if the tank is new or nervous unless they speak up. Thus pulling for the tank automatically is going to put them more on edge if they're new or inexperienced which in turn is partly why there is a lack of tanks and the queue times are so high for DPS.Healers pulling really doesn't help because then the tank has to work even harder for aggro all while the healer either has to stop all actions including healing for a precious few seconds but if the pull is too big and the tanks used thier CDs already causes a wipe with most of the inexperienced and new tanks again a contributing factor as to why there's never enough tanks
