Shadow Tracking: Weapon Camo Challenges. I noticed that we have to complete one full challenge before we move to the next one. As I understand how and why this is the way it is, it would be nice to have challenges have progress toward them even if unlocked. As an example, working on your Carbon Weapon Camo can actually progress head shots toward the Gold Camo Challenge. During the grind of 250 kills for the first challenge, I had gotten well over 50 headshots and to have a system that some games have done in the past would be a Great Leap Forward for these challenges. From Carbon - Gold only those 2 challenges to be tracked in sync with another. If I’m chasing 250 kills for carbon, any headshots would tally toward my gold challenge. You could offset this by increasing the total amount required by 60-80 and it balance itself. It might be worth looking into this. However you guys are able to make it work.
