Re: RQ: Could you make "Reset progress" button in Battlelog
Hello,
This could be because of: "Logging into Battlelog, you may find that you are missing stats, or your platform stats appearing under the wrong platform.
Rest assured that your stats are safe and that we're tackling these issues and will have the issue fixed shortly."  But with bf3 premium you can now reset your Score/Minute, Kills/Deaths, and Wins/Losses stats if you want a fresh start with your multiplayer soldier.
