For me, as someone who spends countless hours creating vintage rosters
1. Replace that color wheel with some RGB sliders and the ability to enter the hex code for the already known color of a team.. trying to make small adjustments with joysticks and that color wheel to find that perfect color is nearly impossible.
2.Let us have full customization like in CHEL, let us have all the outfits and cool stuff available in offline.. I don't play CHEL at all normally but I'd consider it if I could unlock more skins for offline custom teams ( I mean come on who wouldn't love creating a team of short players in elf suits for Christmas! haha).
3.Let us create our retro rosters and give us the ability to remove helmets! Let us have the ability to adjust the alumni players current ages... give us some retro gear and goalie masks.
4. Can we please gain the ability to randomize attributes? I'd love this for making custom throwback rosters it could speed up the process when making those AHL depth players. example: set player overall at 68 and hit "randomize" with X button a few times and voila!
A little off topic but along the same lines of creating custom leagues with throwback rosters
5.Enable full customization in franchise mode.. why not have this option? additionally to this .. let us be able to control every team if we wanted to
Note: Was going to add in "manually enter contract $ amounts" but it looks as if this will be in the game according to Tougie …so that adds years to life lol
