Since most dungeons are speedrun I will goad the brd/drg/mnk or other nin if there is a PLD or the WAR if there is a WAR on the big pulls. If they need it for any other situation in a normal dungeon they need to learn to manage TP better.

As Mnk I always assume that I run out of TP first (even with invigorate) in prolonged boss encounters so would likely to Goad them if the fight goes on too long.
