Destroyed MMR
Simple question. I was earning 30 points per game, at silver 1. My mmr according to op.gg and various other websites was around the platinum 5-4 range.
My brother started playing again after 2 years, and has lost a lot of his skill. Needless to say, we duo queued together and lost an amazing amount of games, and I dropped to bronze 1. I now earn about 15 points per game, and lose 20 per loss. My winrate which was once around 65% is now at 42%.
Here is the question: Is it possible in any way to get this account up to diamond? Or is the MMR permanently damaged due to queuing w my bro and losing so many games?
Should I start a new account? I would hate to not get my main to diamond because I have so many skins... but winning a few games in a row I'll only get 45 points, but if I lose 3 games I'm down 60 lp. Is this possible to fix??? Or is this account destroyed?
