This scenario is so rare, Cure III is almost never a good play. Medica II is straight up +400 potency over Cure III with a far better range. Plenary + Rapture is equal to a plain Cure III. A single mechanic on P3S is one of the few places Cure III is worth it and that's only because it's literally designed for AST and screws WHM over badly.
