That sounds... impractical. The "HQ" has been a staple of Battlefield games, hit escape and you've got full access to the server browser, soldier stats, friends list, etc. all while remaining in game. It was bad enough in BC2 where you had to leave a server to access the server browser. What does one have to be smoking to think it's a good idea to make people leave the game window to access a basic feature of the game?
