So, I was thinking that it would be cool to sometime in the future seasons have unlockable armor coatings from ranked matchmaking. These armor coatings would represent the highest rank you’ve achieved that season.
For example, coating from diamond rank could have details of diamond texture on it while the rest of the armor would be in some other color (having the entire armor coated in diamond wouldn’t look very good imo). Onyx could be similar to how Black steel characters looked in Gears of war 4.
Coatings that depict your highest rank would be far more interesting than stickers on your armor, weapons or vehicles imo. Especially since there are much better-looking customization items available.
