http://na.op.gg/summoner/userName=impressionist Click check MMR. If you don't wanna click it, this is what it says

Welcome to ELO hell. 1,244 MMR Too many duo games! MMR might be inaccurate. A baseline MMR has been changed by the latest Riot patch. (2016/5/27)

Basically, your MMR is sht. You're Silver 1 and the rest of the games you're in is filled with High Bronze and Low Silvers

how do i check my mmr?

I was placed with a bronze 5 on my Gold Promos. I still got 20 LP every win.

How did he get a shit mmr with a winrate above 50% tho

The main reason I went from G4 to G1 in like 2 days is mainly my mmr being 100 points over standard, so I gain like 25 Lp a win, and get 15lp a loss
