Losing LP because of afkers mid game is absolutely ludicrous

I will never stop being amazed at how other players are punished in the ranking ladder because a few players decide to say screw it and leave the game. It's happened many times; I just got out of a game where EVERYONE on my team decides to RQ and sit in base in less than 10 minutes. I can't do shit but 1v5 at this point(which is pointless since enemies snowballed at this point).

Is there like a legit reason I still lose LP and get punished for my team quitting on me? Please give me the quote, or link to where this is what happens. Was I supposed to beg and plead with my team to pleeeeease come back and play? Was I supposed attempt 1v5 and get the same shitty amount of LP whether or not my team played and we won? Like...I don't understand. It's already a hell of a grind just trying to rank up, and I'm not gonna deep dive the ranking system too much here, but we already know that its a grindfest full of long ass games, thats a fact. What I'm getting at is that ranking is already hard enough with the current system, it just really really annoys me I get punished for my hard work in previous games to get to the standing I was at.

It's not the end of the world, and ranked in league in the grand scheme of things means absolutely nothing to the average joe who dedicates time to this game for whatever damn reason. HOWEVER, that being said, if I'm dedicating time to the game, and actively trying to improve; I SHOULD NOT BE SET BACK BY PLAYERS WHO CLEARLY DON'T GIVE A DAMN ABOUT THEIR STANDING IN GAME.
