So I was about to win against some one, when 'communication was interrupted' comes up and the battle ended then and there. When I moved on to search for another battle, it appeared the last battle didn't count even as a battle, much less win/lose. What happens to the other person's online stats? If this is how people are getting good online win stats, this needs to be fixed, NOW.
You're experiencing a degree of anger that causes a person to utterly get annoyed with the game and they may even yell such words, hacks! (hax) , cheater!!, and even the occasional "frustrated groan."
Currently what happens is, whoever disconnects gets that loss counted against them. It doesn't benefit you to rage.
