Something this game REALLY needs
 

You know what it is? An auto-kick system dumping automatically any champion that doesn't move at all in champion selection screen by the time counter reachs zero. That way, people wouldn't need to dodge to avoid a lame game with a random afk player who just decided to accept the matchmaking pop-up but was actually never there :/

EDIT: And with "doesn't move at all" I mean it doesn't choose champion, change masteries, rune/mastery pages or spells. Game should be able to easily detect when someone does that.
