I thought it was sooo awesome that they managed to implemented it. Since they can do it, I wonder why nobody else has been able to do so. Since it means that consoles do provide the information to the game that if they are using Wifi or Wired.
I accepted all kind of matches during my play and it seems Wifi is the main problem. But that isn't surprising really.
Several fighters do this. Injustice 2 definitely does. Pretty sure even doa5 did.
