Leavers, AFKs, DCs

Leavers, AFKs, and DCs. Before this past week, I haven't really been too bothered about them. Until my last bunch of ranked games that i recently lost. 5/6 games I had 1 person just either sitting in fountain, disconnecting, or just leaving because they didn't get the role they wanted. It's becoming an issue and really just makes the game unfair for so many players who are good at what they do. It's sad when you lose LP for absolutely no reason at all. Riot should make it so that if you have a DC/Leaver/AFK on your team, you don't lose LP.
