RIOT PLEASE

I am tired of always being paired with afks. It's really making me unable to enjoy ranked. I cannot stand losing 3 games in a row due to someone being dcd the majority of the match, then the entire enemy team manages to feel the need to talk trash about how they won 5v4 even though they almost lost the match. Would greatly improve gameplay if afks were punished more severely would encourage people to not afk the entire 40m long match.
