Afk/Leavers and LP

Lately I have had a lot of leavers and afkers in ranked games, so I am losing LP that i cannot control. I think it would be a good choice for riot to put something in to make it so if someone rage quits or internet crashes and they are idle for the entire game in base that you shouldn't lose LP it should be a "loss prevented". Honestly though, I guarantee everyone has been in a game where they have no control ever if they are super fed like 100-0 and they just cannot win because of the one guy who got mad after he got ganked and then said "screw this" and left. I really hope riot will take this into thought and make it so if you have 4v5 for some reason including afk, rage quiters, or internet problems that they make it loss prevented.
