Totally agree with most of them, but I think as a IGE user for 3 years, we need more control of "freedomness" to edit something we are unable to do that at this time. @Marc Vaughan
I have these shortlist where I think there's a chance to be added into FMM 20 and/or its next generation. I hope so..
• Possibility to change, remove, or add both player's 1st and 2nd nationality.
• Possibility to add, remove, or change player's stage name.
*We knew Ronaldinho Gaúcho both IRL & in the game, but we barely know his actual name is Ronaldo de Assis*
• Possibility to edit player's caps and goals with national team.
