Armor cores and coatings

I think we can all agree that the armor cores and coatings make the customization extremely disappointing :disappointed: I unlocked Carter Kit and you can’t do anything with it. Why was it designed like this? You guys said we’d have millions of options to customize our Spartan but it’s one of the worst things in Halo. Halo Reach is 100x better than this. Please fix this​:blue_heart:
