The more i am playing sage the more i feel like its essentially just scholar with a skin the majority of sage actions have a direct translation to scholar. Kardia is esentially a targeted embrace, physis is essentially WD+Illum, ixochole is just indom, kerachole is just sacred soil even sharing the same 78 trait, taurochole is excog(this one is a bit loose), druochole is 1 to 1 lustrate, pepsis is emergency tactics.
Addersgall is probably the only thing it deviates a bit from sch but is also just aetherflow with a small twist, instead of getting all 3 at once you gradually generate them and instead of getting 20% mana at once you get 21% by using them very similar. Pneuma, Haima and panhaima are the only actions that differentiate sage from scholar.
Ast while does have analogues in whm it still feels quite unique with cards, minor arcana star etc. But sage doesnt feel unique at all it just feels like 90% scholar, this is just my personal opinion.
