I have just been demoted, back into silver 4 due to trolls, afkers and players who aren't that good..... Why and how can this be taken out on me? I find this hardly fair. I think instead of looking at loss or win of the match, you should be basing LP on the individual player and how they managed to do in the match. Kind of like champion mastery points. I find it hardly fair, and extremely disheartening to be DEMOTED due to something i had no control over. Please look into this, I'm getting really tired of being pull back by other people.
