For the rest, who was able to play the online say that even with these bug (predicted from Team NINJA that indeed is asking to the players to compile a form purposefully adressed to the Beta testing) the online experience is the best so far of the DoA5 series, even compared to the next gen consoles.
On another side apparently there is a bug and all the players get the notify to own a strict Nat (even when this shouldn't be the case, however there is no way to have a sure confirm if the things are so).
