Away From Keyboard (AFK) Players

Greetins everyone. I have been playing League of Legends for 6 years and i have experienced preety much every change. But there is only 1 thing i will never ever understand. And that is the AFK players. We all had one or two or three or maybe even four afk players in our team once or twice! The only question is what RIOT could do in order to stop AFK players. Well RIOT came up with a wonderful idea of banning an AFK player for 5 straight ranked games putting him in a 20 minute queue. Thats acceptable and wonderful. Even more than that RIOT came up with an idea of perma banning AFK players if they leave so many games of course. BUT! AND I MEAN! BUT! What if that dosent help? WHAT IF RIOT SHOULD START CONSIDERING OF HELPING THE PLAYERS THAT ARE ACTUALLY PLAYING THE GAME. For example. I played a game 2 minutes ago where a player was AFK since the first second of the game. We lost of course. But i mean. Why do i have to lose 20 lp cause of that? Is that fair? AFK players will keep leaving even if you ban them for ever. *My main idea is this. -If a player has been AFK for more than 20 minutes in a game then the team should not lose lp! You could tell me that's not right cause if your team is losing then someone cuold just leave in order for the rest of the team wont lose lp. Yes of course thats acceptable. BUT! 20 MINUTES? That means that the team was able to hold the enemy team for 20 minutes! Im just tired of losing lp cause of 4v5 and 3v5 matches... It is just so unfair. I hope RIOT could see this and maybe try to consider it as a solution.!
