NO MORE PUNISHING FOR PLAYING 4v5

Why do players lose LP especially now since its the end of season and the fnal climb is on when someone decides to AFK in the middle of the game ?!

Recently many players have been leaving the game after few minutes of playtime due to either flame or ragequitting or other reason... so why do we have to lose LP with him ??? Why isnt the system deducting LP just from him/her + the low periority queue while other players on his team get a loss prevent, as for the enemies they win LP as normal. AND IF the 4 player team wins, they get LP as normal while he gets none.

I think this is a good solution for the system at the moment, as many trolls have been messing up games by cheating the 5 minutes for remake, and leaving after that, or simply staying in base to avoid the punishment.
