AFK S AND LP

I have been playing solo q in NA for over a month and other than being a really bad server I can state that I found people who loose lane and afk after, almost everyday, I think there should be a system that should recognize this and it has to give some way of payback in the lp of the team who had the afk by reducing the amount of lost lp or keeping the same lp income as before loosing the match.

A change like this would reduce a lot of frustration in the ranked ladders but at the same time it could implement a double multiplier of lost lp in the afk players accounts to prevent a rise in the amount of leavers and improve the overall quality of the game.
