After 44 resets I doubt he remembers how to gunsmith, but I would pay an ascendant shard to change masterwork on my almost god roll weapons. Edit: odds of getting a god roll - barrel, magazine, perks and masterwork combined - are below 1% on average size perk pool (RIP Bottom dollar and Royal entry). Odds of getting a good roll are slightly higher. Considering how rare some weapons are, I think we should have control over certain elements of the weapons e.g Masterwork (maybe barrels and magazines?). I’m sure Bungie is working on a solution.
