Same in the other game. "Professional" seems to be the "realism" mode, but with no challenge (on PA1/assisted anyway, which I feel offers the most realistic representation of a player's abilities).
Neither game seems capable of providing a challenge without both turning the players into aliens, and removing all football realism from the game (making players psychic, and tiki-taka easy).
My question is - is this because the code isn't complex enough, because the processing power doesn't allow it to be? Or... Is it because AI is developed purely with the online game in mind now (hence why, in PES, your defenders occasionally step out of the way on purpose, and in the other game, defenders are total mannequins)?
My fear is that it's the latter. In which case, it will never change.
