An important change is coming to your Battlefield 4 experience for PC. The new Battlefield user interface will be introduced for PC players in early Spring, 2017.
Braddock512 – EA Community Manager: This latest UI update provides a more intuitive and centralized experience for all your Battlefield games.
Changes include:
Functionality for squad creation before you enter a match.
A recommendation engine to suggest relevant maps, modes, and more.
A unified user interface allowing you to launch Battlefield 1 from your Battlefield 4 client (if you own both games.)
Note that Battlelog will still be available on https://battlelog.battlefield.com/bf4/ after this new UI is rolled out.
