That's kind of stupid don't you think? after all the kingdom hearts bosses scale with difficulty and that dose not even get NG+. so if you NG+ on light returns you just run around doing quests till get to day 7 and then go kick their arse. well other than Caius ballad who stays the same no matter what. also anyone notice that Caius is probably the second or third FF villain who's dastardly plot actually succeeds?
