hi thanks for your comments and its great to hear you're having a good time playing with it in solo play! i'm glad you noticed the common enemy NPCs, it is indeed there by design.
first is that in most wuxia media there's alot of common fodder, be they bandits, town guards, rival school disciples etc, that's there to be defeated swiftly and in style by the protagonists. the most memorable things about them are what main weapons or technique they use, which is why they are given a martial arts choice.
as my players got higher level, their damage output started scaling higher and i needed more sturdy mooks to give them abit more of a challenge, which is why there's higher level "versions" of the basic enemies.
in general anyone whos had experience fighting say soldiers or towns guards, or those with alot of time on their hands such as nobles, would have martial arts training, but not farmers.
