Would be a neat little quality-of-life touch (i realize the devs generally refuse to put 'blue mage' and 'quality of life' in the same sentence, but one can hope) to have a tank, dps, and healer 'dummy' or npc near the BLU teacher or carnevale entrance to help with aetherial mimicry- (and therefore role-)swapping on the fly, if we're going to continue to be forced to use an external source for that in the future.
(5.45 is in a few days so this might all be moot by then, who knows)
