Well technically the attack fake just begins winding up another attack in order to fake out the opponent but can be interrupted if attacked. What I was suggesting was a double wind up, because that is the only way it can work if it does the same slash and keep the same format of attack fakes? Basically instead of switching to fake it switches to the same strike you were doing which would require the same amount of wind up like if any other attack was switching to it by form of attack fake.
*edit* I am not exactly sure if this is possible though without altering the code much. What do you think Razor?
