Sadly, that's something Fidel can't do either.
As you said, it's all in source code, so whole defensive mechanics CAN only be done right by EA, if they are willing to do that.
I find that attack is heavily in favor this year over defense. Heck keeping clean sheet is a task on its own... Especially vs harder difficulties it's almost near on impossible to do.
Look PC users are lucky to have possibility to edit gameplay with ini files, but demanding miracles is out of question. Console users have to leave with what they were given. Do they moan as much as PC users? Yes (on EA forums xD), but they accept the game HOW it is at the same time.
