4v5 concept

While staring at a screen of -22LP loss on a 3v5 game i was trying to figure out how this was anything near as fair. So i came up with a concept that would increase the fairness of the game in situations such as a 4v5 or even a 3v5. When a player has 'dc'd' or not present in the game for a X certain amount of time the team with the 4 players should have reduced death timers. This could be half death timers for a 4v5 and then half again for a 3v5.

Any thoughts?
