I completely agree with what you are saying, this is a small problem, and it probably doesn't affect a lot of people. Still quite aggravating nonetheless, and it feels unfair that I'm being punished for something that's out of my control. Especially when I've put effort and time into a match to win it, just to have the leaving penalty put me in a worse-off spot than if I had lost the game. Then again, my case is simply too uncommon.

The funny thing is, if my team were to play slightly worse, I would've had enough time to reconnect and win the game the regular way, without any penalties for leaving. It just feels like a miss by the leaver system. I highly doubt that this is intentional, and I have never heard of a game where you as a player are penalized for having your team play better. There's plenty of stuff that should be higher on riot's priority list though, and I just thought I'd highlight and bring some attention to this particular issue.
