Add more Mastery Badges that are character specific. Currently there's only Carbon for, Aeros, Meridian, & Sabrask. You should get Gold variations of the badges when you get Gold on every weapon and Proelium badges once you get Proelium on every gun. This could lead to more upgraded versions in the future to match mastery challenges that come in the future. This add more customization to player cards and also show off your mastery of characters.
