I don't think there's anything wrong with black and white stories existing. Good wins unscathed and all. It's a problem in XIV because the game's story was developing into being a little more than that after 2.1. Endwalker's handling of how the good guys overcome threats can be summed up in that one cheesy cutscene from 2.0 A Realm Reborn where you see all characters yelling "YAAA" flying towards Lahabrea.
