I think AST is fine without Regen/Shield on their Aspected spell.
ES and CU is very powerful to heal the entire party.
Let WHM Regen and SCH Fairy dealing with auto atk on tank.
SCH should share its ability with other healers.
Maybe rework Excog into shield effect?
An instant and powerful shield on a single target (cannot be spreaded with deployment).
Let AST Aspected Benefic and Aspected Helios give a buff similar to Excog.
And change the sect effect.
Sect should only affecting card (not healing).
Diurnal Sect:
Grant you the ability to draw offensive arcana to aid your allies.
Under this sect you can only Draw and Redraw Balance, Spear, or Arrow.
Using Minor Arcana will always grant you Lord of Crowns.
Cooldowns: 10 sec? or maybe longer?
Also possible to Sect swap during battle.
Nocturnal Sect:
Grant you the ability to draw defensive arcana to aid your allies.
Under this sect you can only Draw and Redraw Bole, Ewer, or Spire.
Using Minor Arcana will always grant you Lady of Crowns.
Cooldowns: 10 sec? or maybe longer?
Also possible to Sect swap during battle.
With this Sect effect on card, we can minimize the RNG of our cards.
Sleeve Draw will not affected by Sect. You can get all type of cards.
If you want to Redraw after Sleeve Draw, the Redraw is still affected by the Sect.
