I am living proof that ranked mmr is actually broken
I started this season placed in Bronze 2, Had to deal with some very toxic teams in ranked and was spending time just enjoying the climb instead of trying to skip ranks or anything because once you're placed in this elo even placements have to be a total solo carry from the mid lane/jg or no chance of guaranteed winning. I climbed with a 52% win rate all the way into Gold 2 59lp. Then I duoed with a friend who was honestly very hard stuck. We lost almost every game we were playing and once I got to 0 lp g2 instead of my normal gains of solo win/loss lp at 19-23 per win/18-15 per loss it has gone to this -20 each loss and +15-17 lp each damn game. And if you understand that means that just from playing too many stupid loss games and dropping my wr to 51% started to actually screw my grind as I will lose lp from going 1-1 and if you've ever tried to climb that can be the most frustrating thing to ever fucking deal with.
Another topic I have is the players I am queued with prove riot just forcing me to hard carry from good lanes, or just lose to an enemy player that has 4+ kills over you before you even see them in game. Each game I play I am playing with ranked players 2 whole divisions lower than I am at, making it obvious Riots matchmaking is using an unforgiving system as it seems there is no way to "reset" the mmr to my current rank. After dealing with this problem so much in Gold 4, I finally had gone in a hard win streak to gold 3, won a game and only got 16 lp. The game after that I was playing with silver 2s on my team and gold 4s on the enemy team. I just need to know how to fix my mmr as my overall winrate has always been a positive 50%.
