Ranked LP Balance

I've been playing Solo Ranked for a few days in a row now, and there have been so many people who AFK or rage quit from the game, therefore ruining it for the other four people on the team. I think it's pretty unfair that the entire team has to lose out on 20 LP or so just because one person ruins it for everyone. I've lost two sets of series due to AFKers on the team. Anyone else agree?
