ELo Hello AFK

Can something please be done about the AFK rate at lower ELo's? I have been playing a lot of ranked and I am trying to rank up but my last 8 or so games in a row someone would disconnect part way into the game. It really ruins the game experience, I tried Dota 2 and to my surprise they have a way to punish the people that afk during a game. It is called Low Priority Queue, the player is put on a 3 (or more for frequent afk) game ban from ranked games. Dota 2 also checks after the players load the game to make sure everybody is still connected before the game will start, if someone does not load it will throw you back in queue. Leaver Buster is not enough, people just don't care, If they had an immediate consequence they would think twice before quitting or sitting at fountain, any inactivity more than 3-5mins can ruin a game for everybody on the team. I keep telling myself to just learn Yi and carry games but why should I have to do that? I don't feel like working around all the afk in bronze should be part of the game, I feel like it should be reduced to an effective degree through Leaver Buster. Does anyone else agree that we could use a more effective discipline system for AFK?

P.S. I don't really want to move to Dota 2 because the game is saturated with cc, but it does feel more fair to the player taking the game more seriously.
