I have noticed, and I remember of thinking about it last year too.
I miss the option we used to have in the NHL games before where you could choose how long time the player have been in NHL when you created them
5, 10 and 15 years I think the options was if you wanted to create someone who wasn´t a rookie.
Because now when I do the KHL roster sharing file for example, all 600 players + 150 goalies that are created are rookies for the game.... its little hilarious and unrealistic.
But it would be a very simple and nice fix to bring back the old "NHL Experience" option for created players/goalies.
