LP Loss during AFKs

I know this has been asked many times but I thought I'd ask once more for clarity. Riot what exactly is keeping LP loss buffering out of the game during games with leavers? Especially considering the new leaverbuster system that triggers red at the end of a game where a person DC's for a certain portion of the match it could trigger whenever that triggers. Seeing as it's a team game I feel like it would be fair to at least reduce the LP loss by 20-30% since you're missing 1/5 if your team (a lil bit more than 20 generally bc the extra body and general damage in teamfights equates to a bit more that a fifth of the team. Even if you don't remove LP loss entirely I feel like it would be fair to give those who do face such circumstances at least relatively less loss of LP in games where a player afk's for say half the game, because to most people, myself included it doesn't feel right to lose 20+ LP in a game where your whole team is playing handicapped. Thanks for your response in advance.
