A System to Deal with AFK Players

So AFK teammates are a big deal and are pretty common at lower ranks. Having an afk player on your team makes the game much harder to win and i'm sure that most players are frustrated when they lose ranked matches because of it. Currently there is a system that focuses on punishing AFK players by making them wait timers in low priority que. However this does not always solve the problem at it's root. That's why I came up with a simple idea that could work alongside the current system. It would decrease the LP loss if there was an AFK on your team (except for the AFK player) and vise versa if the enemy team had an AFK. Of course this would be slightly exploitable and you still have a chance to win, but that's why it only decreases LP loss. If you don't wuite understand my idea it works similar to how valve restores previous ranks to players that played with cheaters. Another idea would be giving some sort of advantage to the team with the AFK such as a minor stat boost or bot.
