- WHM had Shroud of Saints which turned into the role action Lucid Dreaming.
- AST had Luminiferous Aether (I think that’s what it was called.) And back then, the Ewer Card was an MP refresh and could be buffed to double potency, double duration or be aoe, and then it could be further extended in duration with Celestial Opposition and Time Dilation.
- SCH had and still has Aetherflow and Energy Drain.
- (BRD also had an AOE MP refresh with Mage’s Ballad (ARR) which turned into a ranged role action Refresh (SB) then got deleted (ShB).
- Casters also had Mana Shift to help in SB.)
I like that they had more identity with their MP skills in the past but really they still do. The problem for WHM is that it has the highest spell costs while not getting its own MP skills until after 50, (while AST’s Draw is at 30 and SCH/SGE get their MP skills at 45). Assize (56) is barely MP positive at only 500 MP and Thin Air (58) will be nerfed soon but doesn’t generate MP, it only conserves it. The simple fix is to move Aetherflow and Druochole to a lower level for SCH and SGE, but WHM would need something new probably.
