Idea: Loss prevented for AFK's in the team

Hello there, i would like to share my thoughts about the concept of AFK'ers in League of Legends. Although a lot of people can't help when they are afk because of numerous reasons, such as internet disconnections or crashing pc's. Now, the AFK'ers team is in fact punished because they lose, while it's almost impossible to win 4v5. This has happened to me so many times and even got me demoted 2 times in the last week. Riot, how about rethinking the loss prevented system and making it more common for someone to get a loss prevented when there is an AFK in the team? In this was you will get a much better ranking of how good players really are. I'm not saying everyone in bronze and silver are there because of AFK people, but certainly a lot of them can not get out of it (including me), and I am not excaggerating, because there are so many games where they have to try and win a 4v5 game.
