Some sort of system to lower LP loss when someone quits.

I wanted to suggest some sort of system be used, that when a player comes into a ranked game and quits or disconnects, the remaining players of that team, if the team with a quitter or dced player loses, they dont lose as much lp as they would. As that isnt really in their hands, and as it happens more than it should, or people troll or something happens they dc, why punish the other 4 people on that team. Im sure there is someway to implement this into the ranked points algorithms.
