Ranked AFK's

3 AFK's in one ranked game, how can this be considered a loss. League has to implement a system where if someone afk's, the game doesn't count as a loss. Now i understand this can be abused, so the system should not include if a party member afk's. If they're not in your party, you really should not be penalized. there's nothing a team can do in ranked with a 4v5, let alone a 3v5 or 2v5. this is ridiculous. I have a winning ratio in ranked & am constantly getting demoted. how is that possible riot, you need to figure your ranked system out
