Scholar would come back to the game in almost the best state it’s ever been in. It’d be missing some key needed adjustments like Indom, Deployment, and Expedient. Selene would be back but would also be basically useless, although the Skill/Spell speed buffs would probably actually have an impact given how high our stats are numerically. That said, it would also be disliked by a lot of especially modern jobs that don’t want to attack faster.

Assuming the job is adapting to modern system changes like not needing accuracy, DPS scaling off MND, MP costs adapting to the modern MP system, pets not having HP bars, and you’d just need a few adjustments to make it massively superior to the imposter we have now.

Give it Indom, Recitation, and Deployment. Adjust the potencies of DPS actions to meet modern expectations, making sure to keep Ruin and Ruin II as having the same potency like in ARR. Rework Selene so that Silent Dusk was perhaps a damage reduction debuff and a silence, and she had Fey Caress as an AOE Esuna and Fey Wind was Expedient instead of the skill/spell speed buffs, and you’d have a really well balanced pair of pets.
