Endwalker AST has too many buttons, and other issues

[RinaShinomiya]

You could simply merge Benefic, Benefic II and Aspected Benefic together and make it heal and apply a regen, similarly to how Adlo heals and applies a shield. Same for Helios and Aspected Helios.

No. Benefic 2 and Aspected Benefic, Helios and Aspected Helios actually have a reason to be separate buttons. You can't spam Aspected versions of these spells and heal nearly the same amount of HP as using Aspected version once + multiple regular ones. It works exactly the same on Sage. Your suggestion would actually worsen the jobs healing capabilities.
