AST should have one default and one toggled sect

[Limonia]

If people really want to keep the animation, they could make Nocturnal Sect animation when Diurnal Sect is active, and Diurnal Sect animation / Skill when Nocturnal Sect is active.

The problem is that if diurnal is the default, there would be no animation for it. You could have one for activating nocturnal, but deactivating it (to get back to stanceless = diurnal) would probably have no animation.
But we lost so many nice animations already that it doesn't really matter anymore anyway.
