I just finished a fight with poisonous enemies. At the end of the fight, the ground had become poisonous under Madora. Fighting stops, normal time resumes and Madora is suddenly RAPIDLY being status affected by poison. I have to scramble, move her out and throw a heal on her, hoping it's fast enough.
That has zero to do with strategy and is all about twitch movement. Perhaps the developers can let characters stay in turn based mode, even after fighting ends, until the PLAYER decides it's time to quit. That way it's possible to end and clean up in a more tactical manner.
