Matchmaking System Report Option
Since the start of this season it looks like the matchmaking system is "running it down mid" and we often get teamates that are not supposed to be that high on the mysterious MMR ladder. It happened to me few times and one time i decided to request a ticket and this is what i got as a response :
Thanks a lot for bringing this to my attention! I hope this player did not ruin the day for you :( and don't worry, I'm going to look into this right now but please don't forget to also use the report system whenever you can.
I'm not a high rank player and it didn't affected me that much, but it is not fair for the player that got mismatched (in games that are even one full division lower than what the other 9 players are) to get reported.
It is quite simple what it is supposed to do, report the matchmaking system instead of the player himself. It should help the dev team to find the flaws in the system quicker, find some kind of fixes and maybe get few LP as a refound if it proves to be a matchmaking system error.
