Leaver Buster Improovement

I think if a player is Afk players should be able to vote to kick "AFK players only" Or Dced players what ever it be for someone who can fill the roll. I know everyone has had issues with AFKers before and i truly want it to be fair for people trying to play ranked when 1 person goes afk its still possible to win hard but possible but when you have 2-3 players afk in ranked really......this needs to have some kind of replacement method to make players who dont afk and actually are trying a chance i tend to see 1 afker every 3-5 games this is horrible on promotion series ect. please try to come up with a better solution to afkers in game i see people join say brb and be gone for 30 minutes of a game they should be replaced to give a team a chance. on solo/duo this makes since of course on 5 vs 5 teams it wouldnt but i would like some feed back on this idea because good players shouldnt suffer a forced loose because of trolling intentional AFK's
