Meh, BS? That's exactly what those challenges are for though. They are challenges to get you to switch around different guns/playstyles that you might not normally play.
I'm conflicted on this one.
On one hand I agree it would be nice for newer/free players to get a bit of a boost.
On the other hand APB is meant to be free in creating and using and showing off whatever you want so it would go against that.
I would rather see hair gradients/streaks added as a customization option rather than just straight ability to jam decals on the hair.
We already have a hue slider?
