I am pretty sure the elemental magic is WHM's
Core Essence which was taken away in Shb. Glare replaced Stone. The wind magic was also removed and got replaced by a light-based one. The cast animation for Aero III actually looked good, better than Misery in my opinion. The white fluff initially came from the Lily system which looks completely random IMHO. You don't even have a job quest linked to a spell that interacts with the gauge. The job gauge needs a rework from the ground up, the whole concept about the lily system is bad and out of place. Holy is the only light-based spell that WHM originally had which again, doesn't interact with the gauge or at least hasn't been interacting with it for the past 8 years.
Whenever I recall
Y'shtola's role play duty I keep thinking about what Whm could have been. When I was doing the MSQ for the first time, I did it with WHM and when I completed that quest I kept trying to find that spell somewhere. It wasn't the Temperance, it wasn't Misery, so thought it was hidden behind some quest or stuff but I was mistaken. The reason why I was so certain that we had a spell-like that was that Yugiri used Bunshin somewhere in Stormblood and then I checked if Ninja has that Bunshin ability and they do. They received it in Shb if I am not mistaken. I think maybe, in some far distant future we might also get an ultimate spell like that one when WHM gets a decent rework.
