Improve the league-system

I guess, that there are many people who have ideas to improve your game. What we all might have realized is, that it is not fair, when people disconnect or not even connect and the team has to pay the price for it. For example: I climbed to Silver 1 and got into a game where my jungler disconnected after 10 seconds. e lost and i was demoted to Silver 2 again. My whole work and playtime for nothing. And here is my point: Could you make a system running that figures out when a player left (should not be that hard) and avoid the team from losing LP, because of this? I do not think that it is fair, when someone has the right to ruin others "work" without getting punished. Many players ignore messages, you sent to them and I think that this would be a "more fair" way to deal with early ragequitters or just connection problems that are not caused by a player hisself. MfG
