LOSS OF RANKS POINTS DUE TO AFK PEOPLE

Ok i recently sent in a ticket to riot games and they told me to come to the boards. When i read on the boards i only see the players responding and not the actual RIOT gaming employees. I would like to know the answer to this simple question. If I am playing a ranked game and a person on my team never connects to the game at all the entire game. and we lose why do i lose my rank points. that seems a bit unfair. I don't mind the loss because i played the entire game or left at the 20 minute mark. But i don't think we should go down in rank and lose our rank points because some team member never connected either because the new patch is messing with their game or cause their computer is messing up. I just wanna know what can be done or what is being done in the rule book to fix the issue and stuff. IF anything at all. Any answer would be helpful. thanks
