Demoted due to afks.

Why the fuck has there been nothing done about afks and people who leave games. I have been demoted countless times solely due to afk. I'm tired of the bullshit statement "you can win games 4v5." It's such a slim chance and something needs to be done. Had 3 straight games with a dc/afk and yet I still lose full points and end up getting demoted because of it. Please realize this unfairness and do something about it.
