My biggest issue with the niter plan, besides the many other problems that have been pointed out, is how annoying the guns lobby has been.
Guns in this quest have consistently had a advocates who propose a limited "common sense" action involving them. "Just get one more handgun", "just get dwarf help for this bit here", and so on. None of these are necessarily bad by themselves, but in total they result in a larger overall focus on improving guns.
Having such a repeated focus on something that I am not interested in (as it feels like a stealth uplift) isn't something I want to see, especially when every time we are assured that this will be the last time it comes up... until another gun related shiny appears.
