The gameplay should be updated.
It is very easy to block xray/fatal attacks. It is very predictable. You can see it coming when the screen colour changes.
But Players like sub-zero who have the ability to freeze the opponent, before they perform the xray/fatal attacks, have the upperhand. This makes them cheats, above other players who cant.
An update should be done to level the playing field for all players. All Xray/fatal attacks should be made unpredictable. Like previous versions. So that players who cannot freeze their opponents, will also stand a chance
