What he means (i think) is that weapon upgrades aren't necessarily bound to the guilds. In call of warhammer for example there are differen't non-guild buildings for each weapon type (ranged, meele and firearm). I don't think that more than one upgrade level is possible in the med II engine though. I guess his point is, that you could make similar buildings for tatw as well (except for the firearm thing of course) in CoW they are called fletcher's workshop and weaponsmith or something like that. As i am a big fan of upgrades, i would apreciate that too and am looking forward to a baron's version of your armor upgrade system.
Great submod btw.
