Well the Hero will become more OP and probably there will be more human characters too that you can get better equipment and more variety of spells e.t.c. Maybe you can be able to create custom heroes choosing hair color hair type skin color shape of body e.t.c.
If code combat followed this then code combat will explode! Though now with the characters there will have to be more worlds and more advanced code to become more creative!
Maybe there could be more hero types too like assassin, dark mages, e.t.c.
