Got almost nothing but desyncs tonight. Played one guy, good connection, his name was I believe KimKPhwan, a Mexican dude judging by the flag in his avatar. It was actually pretty good. Got 2 sets in with him, then it desynced. And every person afterwards desynced. We'd get to the character select screen, synchronising message would pop up, 15-20 seconds later an opponent has left the match message would come up. Every time.
Hope this is patched
