Something has to be done about losing large amounts of lp when you lose ranked games with afks

Its not fair to lose 20 or 30 lp on a game when you have more than 1 afk, its difficult to win with 1 missing but when theres 2 missing its basically a free win for the opposing team. There needs to be a system that recognizes that if there is an afk you lose only a certain amount of lp like 50% than a normal loss. if there is 2 afks then it should be like 25% and so on. I dont know if others are having this problem lately but its been frustrating as of late. Im not trying to rage or anything im just saying i feel like its just an unfair system when you get punished for something you cant control.
