They are just too common, you will go on a streak of wins and then suddenly all the work you have done is undone and you get massive loss streak. You log in the next day or next session and it goes back the other way.
Its like you can predict when you will start to queue and just have no hope in winning the games and you are just plunged into a loss streak… you play and play and just lose.
You log back in and then you streak wins… infact I have games where I have left, come back and have had very little to do and you just win.
Manipulation at its finest or some of the worst competitive matchmaking I’ve ever seen.
