Can I get my LP back?

I think Riot should look in depth at games that have players who disconnect or troll/int. I'm not saying they should look at every game, only the extreme ones, like the games where teams are winning but then someone disconnects or starts trolling and throws the game. It's not fair to anyone else because 4v5s are not fair at all, and you have no control over what your team decides to do. If someone on your team's computer crashes, you can't do anything about that. And even if you were ahead, now it's a 4v5 and the game is most likely lost. It makes no sense how I can lose LP for stuff like this because it's completely out of my control. If I'm in a game where we're down 20 kills and someone rage quits, then I don't give a shit because we're going to lose anyways. But if I'm winning a game and someone throws it, then what am I going to do about that? They give LP back if their servers have something wrong with them and people are in a ranked game. And that's a more extreme case, but there's still nothing anyone can do about it at the time that it happens. Make games like this a loss prevention, but the other players can keep their win. There's nothing wrong with that, is there? Riot... you have the most played game in the world. Please do something about this. I'm tired of losing LP because of things I can't control.

TL;DR: Riot should give back LP if you're winning a game and someone on your team disconnects or throws
