One sided games and intentional feeding grows exponentially as you approach Diamond V
I stopped playing for a while and decayed from Diamond IV to Gold I, and my MMR when I returned was around Gold III because of inflation. The players at Gold III were SIGNIFICANTLY better, on average, than the players I'm getting around Platinum II MMR.
Every single game is a complete stomp for one side, because one or more players are playing so badly that it's indistinguishable from intentional feeding, or someone is trolling because they're auto-filled.
See this auto-filled support TF I just encountered, as an example. This is a regular occurrence. Sometimes it's intentional, sometimes it's not. https://i.imgur.com/TkCDSzh.jpg
I was Diamond in S3, Diamond I in S4, and Diamond I in S5. In S6, I waited until the end of the season to play post-decay, and I absolutely could not get past Diamond V because of this exact problem. It's now S7 and the issue has gotten much worse. I can barely even get back to Diamond V, because games are essentially over before they start.
Is anything being done to deal with this before the next season begins? It's really fucking sad that a blind eye has been turned to this, with virtually every Diamond player complaining about it.
