A pop-up on screen like the Sephirot Battle challenge flashcards would help so much with jumping into old fights I've forgotten, or players entering new fights without researching / watching videos first.

For such a rule-based combat system with a lot of binary "right" and "wrong" reactions to make, it would help a lot to just give players a basic fighting chance before entering a battle — one that doesn't rely on a party member volunteering to type it all out in chat every single run.
