Ban AFK player more consistently
All right enough is enough, I get afk players at least 1/6 games, it makes the game absolute shit. It is past time Riot adresses the problem, either by banning more consistently the player, or by diminishing the cost of 4 vs 5 loss, but I'm just done.
(And if it would causes problem with people abusing the system, just dont give loss dimished bonus to the premades of the disgusting AFK player)
