Its been a long time since i played Vanilla P4, but Rise never jumped it to battle like that before right. I know she did not do all out attacks, but did she do the other things?
Depends on what you mean by "the other things". I'm currently playing Vanilla P4 and she does learn a bunch of skills by either leveling up or advancing her Social Link, ranging from detecting all treasure and shadows on a floor to replenishing a percentage of the party's HP/SP.
What i meant by other things is her jumping into battle to cure status ailments or raising your defense.
She did nothing in battle in vanilla other than analyze and say a random weakness/null on enemies.
