Pretty much every match is at least 1 division in rank range, very rarely is everyone the exact same rank. The amount of MMR you lose or gain in a single session, or in a span of just a few games, cannot account for the amount of skill disparity between teams from match to match, and cause the consistent stomps.
You’re basically saying that if I win a game or two, my MMR goes up by so much that I get put into a match with people I can’t possible keep up with, therefore I naturally lose the next few games. Surely you see where the issue is with your logic.
By the way, for some context, I came back to the game this season to play seriously again, and started in P1. The last time I played properly was around S4-5 and I was around high masters/low GM. This season I climbed from my initial placement rank of P1 to D1 over some 130 matches with a 59% win rate. Makes sense, right? Except the instant I got near masters I went on the worst losing streak I’ve seen since 2016, and now, about 100 matches later, I’m fighting to stay in P1. If I drop to P2, I’ll be the lowest rank I’ve been since OW2 launched, and even lower than I was in OW1. The majority of the matches in this massive rank drop were likewise some of the worst I’ve ever seen. Most of the time there was absolutely nothing I could have done to save my teammates from themselves.
So either something is very much out of whack with the matchmaker, or I’ve been drinking a whole lot of silly juice in the past 12 months and have somehow turned into the worst player I’ve ever been.
I main Ana, so I’m watching my teammates get hard diffed in real time. I can predict with a very high degree of accuracy that someone is about to do something dumb that’s gonna get them killed, and exactly what’s going to kill them. I made a little mini game out of it.
It’s got to a point where the enemy teams are starting to acknowledge that I’m essentially 1v9. I’m basically smurfing at this point but the game seems to think I need to be even lower than I already am.
Oh, and my win rate is now negative, something I’ve never had before in my entire OW career. From 59% win rate to sub 50%. Curious, isn’t it?
