I bought this game yesterday and after having it upgraded, I start playing the game, but I always get disconnected continuously, which I really can't stand anymore. Just now I got disconnected for three times within 7 minutes probably.
But I see you guys don't have connection problem with this game. Maybe it's because the problem is game server itself, or the place I live in, because my native friends also say this game lags an asshole on both PS3 and PS4.
