Ranked Flex Matchmaking

So I'm s1. And that's definitely my rank, I don't play a lot of league I have about I think 50 games on ranked flex. Anyway, my party consists of Gold 5 and Gold 5 so not huge differences. The team we got were: S1 S1 G5 G5 S2. The team they were: G3 D5 P5 G2 P2. And there ahri had over 800 games, and the rest were similar. What the hell is this ranked difference? The ahri was complete trash for P5, like hell even I play ahri better, but still the rest of their team were just at a completely different skill level. Anyone else had experiences as bad or worse than this? [sg-ahri-1]
