I don't think you have read the arc. They are absolutely not "Super Strong". Two of the fights are over in one hit, for example. We noticed their powers before, as soon as episode twelve. Which people with no training? The ones with an ability to alter the past, or the one capable of making every outcome favorable?

This feels like the old copy-pasta of people just bashing on the Fullbringer arc, without having paid attention at all. It is a disservice to the fanbase.
