I have used it since it first came out with BF3. And now i use it for BF4. Reason i use it is it gives you access to a lot of things that you would have to do in game or in test range and it also made my life easier when it also brought all my key bindings over from BF3 including joystick bindings. Hope this helps. All this program does is create a config settings editor for you. But i have always and will continue to never run it when playing the game so its not loaded up into memory. Also on the site for this settings editor. Its states its PBB safe. And also i have never heard of anyone what so ever getting band for using this editor.
