I would believe it if someone told me the author is a huge medicie otaku (?), like every other aspect of the story seems to have little thought put on, we don't see Falmas trying to be more approachable and hell sometimes he forgets he's in another world saying things like "it's official name is" , also I don't know economics much but how does a guild that's free to join offer training etc. is profitable?
Well I will keep enjoying this series as more benign spin on the whole power fantasy genre where instead of the protagonist getting a harem the world gets a little better
