The city slicker barbarian. It's painful.
In my opinion, it encapsulates everything that's wrong with the genre. Watered down flavor, everyone can be anything, a barbarian son of a merchant, sure, he just gets so mad and fights hard, cool mechanic for a city boy.
Culture and setting matter to me. A barbarian should be considered barbarous by the typical city dweller. Feared, perceived as savage even. But no. It's just a mechanic.
