Can we not count these games as a loss?

There must be a way for Riot to make it so that in ranked games, when a teammate DC's or rage quits, it doesn't count as a loss for the rest of the team. Or at least, no LP is lost. For the person who DC's/Quits sure, but why should the rest of the team lose LP for something they can't control? I just had a game where our toplaner DC'd. It was legit according to him, he lost power and upon logging back in the client needed to update. It took him 20 minutes to get back into game, and by that time we had lost almost all of our towers, including an inhib turret, because Nasus happened. I ran back and forth between mid and top to try and stop this, but it was too far gone by the time our toplaner got back. We tried to make a come back but ultimately failed.

So ok, maybe count it as a loss. But can we not lose LP for it? When you are trying really hard to climb, and this happens pretty frequently (I'd say maybe 1 in 10 games?) it really sucks to lose LP from something you cannot control.

Riot plssss.
