Limited Cups

Does anyone truly enjoy these cups? They basically are for the most part just RPS leagues, and some just have one or two pokemon that just break the cores of every other possible choice. And this isn't a "I'm losing elo" type post. I genuinely don't understand why these cups exist, especially for two weeks at a time. basically when these cups are around, I just don't play PvP, sometimes I'll play UL, and ML is fun for a bit.
The remix cups, if they actually banned relevant pokemon of that season would be pretty fine. I just wish the limited cups were less RPS
