Management for the victims and offenders of AFK and intentional feeding in rank game

Dear Riot, AFK and intentional feeding destroyed the fairness of rank game. The team with AFK or feeder always suffers from lower win rate. Can Riot please give some love the those victims on the team with AFK and feeder by reducing the MMR and LP lost of them. On the other handle pushish the leaver and feeder by largely increasing their MMR & LP lost. I think this arrangement can reduce the incident of AFK and intentional feeding as well as make other player have better gaming experience. Thank you for your attention.
