How would you change Nocturnal AST to be competitive against SCH?

It's gonna be so awkward fitting two extra slots onto my keyboard setup for the stances if they make diurnal/nocturnal something you can switch in combat, lol. ;-;

What? AST has 32 actions you'd want access to, 31 if you take off stella but then heavy has its occasional use. 30 if you find aero not much of a benefit vs malefic II (even though it's instant and less mp for the same potency) That's including the stances but 30 or even 29 actions means you need 3 bars anyway, and 32 actions doesn't make you need a 4th.

The thing is, imo, that if you balance AST's stances separate from each other, NoctAST is going to continue being the mess it currently is.

Except that the only problem here is that the nocturnal stance is overall less beneficial than diurnal. So the situation is exactly the opposite of what you describe. One stance is good, the other just doesn't cut it. If you boost both, that statement doesn't change.
