So im kinda missing skins for challenge's option. exsample:
1: 5000 kills with PeaceKeeper (earn 1 special designed 5000kill skin) "the number 5000 burning in the weapon, could be a way"
2: 30000 headshots (earn diamond skin for r-99)
3: 20000 dmg with charge rifle (earn bloody gold skin)
These could be easy or hard, giving common or higher skins. it would be nice to see, and give players something different to do.
i would personally ask for wattson skins, they really need an overhaul...
