AFK forgiveness
This game has been out since 2009 and after 6 years there is still no forgiveness when a team mate disconnects from the game. You know when they disconnect from the game because you highlight their name in red at the end. so why does everybody else get penalized? This is silly stupid, there is no logic that justify's penalizing the entire team because 1 player rage quits or disconnects. Penalize them, but not the rest of the team.
It happens over and over.. and over and over again. Start a ranked game and somebody quits in the first 3 minutes of the game. What's the point?
