Same raids and same factions

I want to share a few things about the raids. In raids; There are 5 raids, 3 types, but normal raids (copper and plastic) and difficult raids (copper and electronic) are the same map, the same faction and the same factions come one after the other. For example; I’m finding the raids of the Firestarters faction. I especially see dawn’s of children and steppenwolfs raids all the time.
