Questions about MMR
So I'm in Diamond V right now and I have 32 more wins than losses. When I play a game and win I only get 14LP, but lose 32LP for a loss. I googled and found out that it was probably because my MMR is lower than my league. I wonder what caused my low MMR. Also recently I have been duo-ing with a friend who is in Platinum III. Was it the reason why my MMR dropped down?
