Hello,
Like some others players, sometimes, my Internet router have to reboot or reconnect. If that happens and everything works correctly, in my case, it take 1.5 minute long.
But when playing ladder, there no one player that is fair enough to wait to see if the other player come back. Everybody just kick after 50 seconds and get the easy win.
I think a better mechanism should be included to avoid this. For example a longer time to wait in case of disconnection on the ladder, or maybe, if the player come back but have been excluded by the other before 2 minutes (2 minutes was the established waiting time in tournaments in GPGnet) the player don't get a defeat.
