Are you really sure the cap is higher on red mage now than in shadowbringers?
Embolden? doesn’t have the decaying stack aspect, displacement isn’t a dps gain over stand-still-and-stab, manafication and the red button both changed too iirc. It’s pretty easy to argue that red mage was made simpler entering endwalker, even with the addition of an additional finisher.
This only shows just to what extent obliterated any and all vestiges of nuance and gameplay in summoner.
