I kinda always thought that some game could do their weapon user classes based on the fantasy socioeconomic classes.
Nobility- Swashbuckler Class- Nobility who learn self defense from tutors for non-battlefield combat. Heavily focused on staying alive and single kill strikes.
Military- Knight Class- Professional warriors of an official warrior culture who make up groups of honorable special combat forces. Role focuses on what their culture sees as special or honorable.
Peasant- Fighter Class- Impromptu, hired, or drafted soldiers who lean on physicality and have a wide array of combat styles.
Outsider- Barbarian Class- Warrior of cultures who tap into the primal world to make up for their limited access to the latest weapons and armor technology.
