Suggestions for some JFF options:
1) Lob-aftertouch is disabled. That is, you can curl the ball left and right with after-touch, but you can't give the ball more height by pulling the joystick in the opposite direction after you have made you shot.
2) Shooting is disabled unless you are in the PBD area. If you, outside this area, press the button in a shooting moment (as opposed to pressing the button where you would then enter trap mode), your player will fall over.
The idea behind the first option is to take lobs out of the game. Clearing lobs would not be possible, so you would have to "play your way" out of defence. Similarly in midfield and in the play approaching the penalty area.
The idea behind the second option is to make KO2 a dribbling game. Good for practice and maybe also for fun.
PS. I know you are very busy. I hope you can appreciate my suggestions anyway, if nothing else then as food for thought.
