and a feature to change colors on your shields/tabards & helms. Hint, barber, wink…
I actually really like this idea. A late-staged, fully professional mercernary group could feasible have its colours on lots of its gear (helms, breastplates, etc). It shouldn’t be as easy as with a barber, because all but the very oldest groups probably have a mishmash of salvaged gear (as they should, given the theme of a mercenary company). But late in the game, this would be cool.
As for the “attach the standard to a better weapon” that’s just not how battle standards work. Throughout history, banners were… well, banners. They weren’t attached to other weapons because they’d make said weapons too unwieldy.
