I relate to this. I don’t want to doubt Riot and the matchmaking system. I get it that from pure statistical logic, win streak loss streak happens. I get it that there is plenty of "bronze to challenger" streams out there.
And each season, when I play ranked, I am thinking that I must have been tilting last time I had a loss streak...
And then it just happen again and I rewrite a topic on the boards. I get a huge win streak, get 60 win rate or so... which is not surprising as after placement I go down from platinum to silver. Been sitting plat for 4 years over maybe 3000 games. Then I drop Silver. Of course I should get 60% winrate, right? Games are easy and I get S-, S and S+ all the time.
But then at some point after these win streak, 60 winrate overall, I get crazy games. AFKs and int feeders in a row... that I never had during the last 50 games or so. It's just really weird. And then, well, of course I lose like 10 games in a row. Until it stops when I am back at 50%.
I am just stating facts here and I believe Riot think honestly that their system/algorithm works, but maybe, just maybe, they should think about it, if so many players encounter that.
Once a Rioter said "after win streak, your MMR climb, and you get in a elo higher than yours so you start a loss streak". I understand the logic. But I had my loss streak in gold 3, after climbing back quickly from Silver 1. I have been stuck in plat 3 for 4 seasons, gold 3 is not "above my elo".
I am trying to help here, I don’t really mind personally I play for fun and to improve, if the system put me silver/gold/plat, so be it. The only thing I wish is fair matchs, not free wins / forced losses.
