if there is a leaver in the game, the rest of your team should not be penalized that hard.

I see this time and time again. I get stuck in 4v5's and its unfortunately past the 3 minute part for the cool remake feature. There should be a very obvious log riot can run to check if a player has been afk for 10-15 minutes in a game. This latest game I was amumu, carrying my team 10-0-10, and our Nasus top finally comes back from being afk for 15-20 minutes. He proceeds to literally get caught 3 times and most of our team goes down with him each time trying to save him, consequently letting the opposing team BACK into the game. 1 time he gets caught in the enemy jungle when EVERYONE has pinged him to leave so that hes not in range of the opposing team while backing, idiot stays there and get caught. Last two are him overextended at top, no wards in river, no top tower, he is right at where the top tower spot should be, and he is underleveled by at least 3-4 levels. GETS CAUGHT AGAIN.

Anyways, what i'm trying to say is that the team that gets PAIRED with a DC like that should not be penalized with lp lost as hard. Maybe like -3 lp. Riot has to have a log that can detect something like that 15min-20min afk.
