3 games with afk temamates in 1 day.

https://na.op.gg/summoner/userName=lDariusXI So today I had 3 games with afk teammates in ranked games. Does Riot just not want me to play or what? 3 games with teamamtes feed /lose lane then afk. How come this hasn't happened in my enemy teams for like months. These people they just do this because the cost is so little that they to the max only get leaver buster. All the hard works I have over the games are just nothing but losing the same amount of LP like normal? I wish there is a system that punishes people harshly.
