A more unique Ammunition System.

Once the system is developed, it can just be reskinned for other jobs. For example, archers would have a Quiver (Chambers), Shafts (Cartridges), Arrow Heads (Bullets), and Fins (Gunpowder). As far as the game data goes, they'd just need three new types of items for the "parts" and a single UI reskin to make it look like a revolver / quiver. Afterall, they lump a lot of the secondary weapons together as "Equippable Projectiles" according to the extractions (merc arrows, mech magnum, phantom cards, etc.)

Now what would they do with stars?
