as a man datto said "if i haven't used the weapon in 2 or so seasons, whether it's a godroll or trash, I delete it from my vault unless it's something special or unique" for example, his 40k kill recluse is something special for him, because he said himself that conisdering how often he switches weapons, 40k is quite a bit maybe, instead of keeping something for what if, only keep things you know for sure you'll use
