I would personally like to see what some attributes mean or affect how your player plays kind of like training from the older versions where you held the mouse over the word and it would explain what attributes it helps and so on. also for an example for attributes is what is the difference between off the ball & positioning?
the game should have more off-field stuff. for example a player might go to a night club or a bar the night before a game, and you should be able to find out and fine or something along the lines of it. same with Irish.
