What do you guys think about a vendor in destiny that sold ammunition for primary weapons that did a certian type of damage (arc, solar, void). It could work like an ammo synthesis were it would max out your primary ammo and make your gun do a particular type of damage for the length of your ammunition only. It might be kinda neat for night falls or getting past the shields of certian enemys in raids or strikes. It would also add another variable that players can deal with that might make it more fun.
