it wont help online when the game is released though so i advise not too, just get used to it, practice, it will be the same in years to come in fifa i pressume anyway, so youll have to get used to it if you play online.
Switching the controls around is allowed in online games though isn't it, you just won't be able to turn off the tactical defending. I have to use custom controls and it's always been fine in online games before...
