Played about 10 GBU battles today. 1 or 2 disconnectors.
I am using this new team ( will post later) that been giving me a lot of success thanks to MixApe lead I am using.
Also another thing that stood out to me was when I was beating this 1000+ win Japanese player on just one move before the match was ending and he loss was he just disconnects. Not as great as beating him completely but still better that disconnectors ;D
