A new queue for busy players
As you know, League of Legends has a strict system to punish player leaving their matches or being AFK for a while. Mostly however, leaving is due to connection problems, hardware issuses or, particulary with younger players, school, lack of time or just your parants that want you stop gaming. With this factors, ther are just two possibilities: risking to get the leaverbuster or not even begin to play. My suggestion for Riot is to create a separate Queue where leaving or short AFK is allowed. To prevent AFK farming of Experience, IP, or key fragments, players leaving or being AFK for a longer Period don't get any rewards.. So, you play with the possibility of leaving the game unpunished, but with the possibility of loosing one or more teammates during the match. Leaving the game could result in a small punishment too, like having to wait 15 min before joining another queue again, to prevent players of leaving the match just because they are loosing or because the game is getting boring. Verbal abuses, scripting and other possibilities to ban a teammate would be of curse still be enabled. I know the custom Games already offer this possibility, bus a separate queue would be much easier and fair because of the machmaking system. Sorry for my bad english skills, I hope you'll understand.
