Is it just me or?

I play Ranked Game, everybody is doing decently EXCEPT Bot or Mid or is doing awfully. They're slowly getting more toxic and saying "FF". We lose the game cause of them. Then i go play Mid or Bot on another game and Me and my Support are doing REALLY REALLY WELL or i'm just 7/2 mid lane. But everyone else then feeds.

Maybe just instant MMR changes but i'll say it was me 70% of the time.
