We shouldn't lose LP if a person afks

Have you ever played a ranked game and someone afks? What am I talking about, of course you have. It happens all the time, we're in a promos, and boom a top lane tank fizz afks. This literally happened to me today. We need do do something about this, and of course as you can see, my solution is that the team on that has the person afk just not lose any LP and the enemy team will gain alittle bit of LP (5-10ish), since you know, they could've won but they could've also lost. So yeah, this is my solution to this problem, please considering and if you can Riot, please return my LP that I didn't deserve to lose because some guy was forced off the game.
