just lost 20 lp because of 4 afks

Really getting sick of being punished for other players going afk...This has been an issue for several games over the past week and don't tell me "oh sometimes it just happens you'll move up if youre good". No. You're dumb if you believe there isn't an element of luck in matchmaking. I made it as far as gold 3 in the preseason (after hitting a lucky streak of non trolls to get at least to silver 1 and climb through hard work from there) only to be placed in bronze 2 now. Gradually made my way up to silver over the course of a few days yet hitting the silver 5 elo hell has forced encounters with an absurd amount of people who simply dont care. They will afk for the stupidest reasons such as if people request the said player not play teemo or players who get angry at a lack of ganks from a jungler and at 10 minutes start to run down the lane to feed (these are instances of what has happened TODAY). But what really sets of off is playing a game where right from the start our mid goes afk and as soon as the support realizes this they leave as well. Then after one death at top lane they decide to hang out in base then the jungler decides to join in. Leaving me as ezreal adc to fight against 5 other champions and end up losing 20 lp because naturally I have to be placed with these clowns in silver 5. But it isnt just 20 lp in the grand scheme. Its hundreds. And I know I'm not the only one. But I'm sick of these trolls having so much power over my progression to the point where its taking 5 times as long to simply move up a division. There has to be a way to fix this. Pit people who arent frequent offenders with others that are the same. Something. ANYTHING. Like damn riot. You got money. You can find a way to make it happen.
