Seriously, there's nothing worst than having a good roll weapon that only needs the right masterwork, it isn't as if we are getting the weapons forever since sunsetting is a thing, just give either weapon smith the ability to roll again your masterwork at a reasonable price, seriously why isn't this a thing already? Ada is supposed to be a high end weapon smith and forge 9n top of that, why can't she make the modifications herself to change the weapon masterwork?
