In ranked play if you disconnect you get a loss. Which is good.
However, in custom games this isnt the case. I see a few players (quite often it is the same player) disconnecting right before their ACUs are killed to avoid losing points. This also keeps the winner from getting that extra point. I think this is unsportsmanlike and isnt beneficial to the community.
Also in custom games, if a player has a problem in the first few minutes, crashes, disconnects etc... and the remaining players decide to rehost the game, scores are calculated and players lose points just for leaving the game for the rehost.
Maybe a few changes could be made to the scoring system. Make disconnects in custom games count as an ACU loss. No scores are calculated if a custom game lasts less than 5 minutes or so.
