The Connection to Your Peer Has Been Lost is cheating and so annoying
When users are losing and they disconnect their console so they don't get credit for a loss is cheating. If you quit the game you should get credit for a loss especially in the weekend league when the rewards are based on the number of wins. This makes playing the game no fun when people cheat like this. Do the right thing and concede if you are losing and don't want to play anymore.
