The class system of E5 differs from that of E4 in that every character cannot assume every class, but rather a subset that best suits their disposition and/or their general occupation. Also, the classes themselves are not so much broad or typical RPG roles as in E4, but culturally-inspired personalities that complement the psychosocial leanings of each character.
