Customization and sharing is probably one of the bigger request items, that I hope they add next year. Sliders, rosters, create a players, jerseys, stadiums. Those are all things that can be done well by the fans. I don't expect EA to sit and make sure that the entire Blues roster is 100% correct. It's a tough job to begin with, and they've got tons of leagues. But a system like Eastside Hockey Manager has where you can import your own "skins" and logos into the game would make a world of difference. Then people could focus on whatever they wanted. EA could make some generic "College" type setup with generic players, teams, and conferences and allow the players to edit and "correct" them. Similarly they could add a "Russian League" and allow players to change that
if they wanted.
This way, the casual fan doesn't have to worry, but the more hardcore fan can download the proper jerseys and rosters to create leagues that their NHL teams could try to draft/sign free agents from. Imagine being able to convince a player like Radulov to join your team, and having to big against other GM's in the game to get them to sign with you.
