[2019] MMR ROLL BACK IS STUPID

Originally posted by HardcoreGamer: just why ... why is this a thing ??

MMR rollback occurs when players you've encountered in Ranked matches are identified as cheaters. Your MMR gets readjusted accordingly to cancel out the cheaters' effect on the affected games regardless if it was a win or loss. We released a dev blog back during the beginning of Operation Burnt Horizon that you can check out here [rainbow6.ubisoft.com] if you'd like a bit more of an in-depth discussion about it. :)
