Player Leaver System

So... I know one thing that everyone in the League of Legends community hates the most is Leavers. A system that I would think could help in preventing this is a system based on percentages of leaving the game.

Basically, you would get punished when your leaving goes below a certain point.

95% - 5 Minute queue in between Ranked games. 90% - 10 Minute queue in between Ranked games. 85% - 15 minute queue in between Ranked games.

So on and so forth until it falls below 70%

70% - 24-Hour Ranked Ban 60% - 48-Hour Ranked Ban 50% - Week Ranked Ban

This system could reset monthly and only take effect when the user has played 10+ games.

I hope this is something that could be implemented or a system very similar to this. It is almost impossible to win a 4v5 and is impossible to win a 3v5 when that happens. And it happens way to frequently.
