Respectfully a lot of these are simply bad ideas to remove.
WHM: Yes, Cure 1 and medica 1 need to go. That's pretty obvious. They should trait Cure 1 > Cure 2 / Medica > Cure 3 (keep the Medica range). Both Tetra and Benison have valid uses (Snap heals, tank busters). Benison stacks with SCH Adlo
SCH in general needs a lot of work. They basically took any good idea and gave them to sage in Endwalker. Mostly in the "2 effects, 1 button" category. Right now, they need something better AOE wise and I think energy drain is the easiest to do since they're not giving back bane. Put it at 350 potency with a 50% Aoe dropoff (After the first hits for 180 each. But they definitely need to figure something out about all those fairy buttons because Sage just does every single one of them better and they're baked into other buttons. Also after playing sage, Adlo REALLY needs it's cast time reduced or eliminated.
SGE As of right now the only "bad" button is Pepsis, but they have no real identity as a "Shield healer". So many of their "shields" are just weak. For example: Taurochloe. It has a full heal and then a damage reduction. Why not have that heal be a shield? Would be a great tank buster button. Panhaima is good for aoe bleeds.
AST I'm terrible at but I know some of their buttons can be easily combined and a few just don't need to be there (undraw)
