Its not really a huge problem, but wouldn't it be nice to have the lobby countdown appear while in the locker room? It would also be cool to have a timer mid-match so you always know how much time is left. The only problem i could see would be the HUD becoming too cluttered, but other than that it would be a nice addition.
Itd be nice if you could alter your loadouts in the loading screen. So often do I get back from my PC (yes theres that much time between games) start fiddling with a class only to get halfway through and go into the loading screen
