Out of 5 ranked games played today, 2 of them had AFKs
I hope that there will be severe punishments for these people (I reported them and put comments of course). AFKers are ruining games, I'm hoping Riot has a system planned in the NEAR future to not punish players who are suffering a 4v5. Even if I was on the winning team against the team with one AFK, I would gladly forfeit my LP so that the game doesn't count for both sides.
This is a dangerously high ratio of AFK players, and I have experienced them often in the 200+ games of ranked I have played.
