2) More Leagues: Ukrainian Premier League, Argentinian Primera, Uruguayan Primera, Japanese J-League 1, Japanese J-League 2, Dutch Eerste Divisie, Portuguese Liga Orangina. Bring back the Turkish League. Also please take out the Irish League, it is by far and away the worst league in the game, a waste of valuable space and the reason I still don't see RBA in the game.
3) More National Teams: Ghana, Nigeria, Japan, Ukraine.
4) International Call-ups in Be A Pro Mode: I haven't seen this concept of Be A Pro since FIFA 10. Be A Pro is completely pointless without this, it's the main reason I avoid the mode and instead play Manager Mode.
5) Better Player Growth in Manager Mode: If you're not gonna put manual growth back in, then at least make sure that our players don't take 20 seasons to reach their potential.
Any thoughts or ideas of your own?
