LP Loss + Disconnects

As a support, climbing is hard enough. I don't carry games, I enable people to carry games.

Just ranked up and my FIRST TWO GAMES in my new rank were going so very, very well... my ADC was fed, we won lane, we were mid-game and things were going our way!

Then the ADC I had so carefully fed disconnected. BOTH GAMES.

Yeah, I know, hard luck. Sucks. 2 losses.

But in the end game screen, the little pics of our characters DOES show that those players had disconnected. The game already tracks our progress, sees our gold lead, kill lead, tower lead, dragon lead... there are multiple charts of this in the post-game screen. In EVERY WAY POSSIBLE, these games were going to be wins for my team UNTIL it became a 4v5. And Riot can see that. Riot tracks it for us.

So in this situation, how is it fair that we're losing LP?

How about something like, half LP loss when a player on your team disconnects? I realize this would be entirely easy to cheat the system... IF IT WEREN'T FOR THE FACT THAT THE SYSTEM TRACKS OUR PROGRESS IN EVERY WAY.

Like, if the game can tell we're losing in kills+towers, and someone disconnects, full LP loss for everyone. You never had this.

But if the game sees we are winning in kills+towers, and someone disconnects CAUSING us to lose, can we get half LP loss? I mean, NO LP LOSS would be amazing, but for an arguable tracking system I think half LP loss would be fair.
