Updated the list with the changes from IIHF Update December 2021.
More National teams (Even if there is generated players like in Japan, Ukraine...)
Slovenia - Have played in WC D1 A for 5 years now (In NHL22 after IIHF update Dec 2021)
Hungary - Have played in WC D1 A since 2017 (In NHL22 after IIHF update Dec 2021)
South Korea - WC D1 A since 2019 and last olympics (In NHL22 after IIHF update Dec 2021)
Also you can play World Juniors with similar to the rosters in 2020/2021 Championship right now.
I think there will be a roster update to that when the rosters are set for this years World Juniors Championship.
The only problem is that you cant change the rosters for the Junior teams, you have to play with the updated roster from EA.
1) You wont be able to add players like Lucas Raymond (who playes regular hockey in NHL already)
2) You cant change the generated players in teams like Russia for example (because EA doesn´t have KHL license)
So I hope the National Team Juniors rosters will be like ordinarie league rosters with rules settings that players younger than 18 can be transfered there....
