Why does this happen?
Last game, I played with this really toxic guy. He wanted to play Ezreal support, but I had already banned Ezreal. He then locked in Yi support with Ghost and TP and ran it down mid. We obviously lost the game as he got the enemies fed and took my cs and exp. Do I get my LP back for this? also, another "issue" that has been happening is that when I win, I get around 15 LP and when I lose I lose around 20 (I lost 23 LP for this game). On OP.GG my mmr is normal for my elo, and it is very hard for me to make my mmr climb right now, but easy for me to make it drop. I have seen this problem occur with many other players as well, but I haven't seen a rioter comment on this. Help me Riot.
