I think, like chaos and dark was stated to be, that it would be too similar if they aren't completely separated from each other. My personal way of seperating them would be that Fighting would be about fighting fairly, Hero would be about those that protect another, and noble is just being honorable. I wouldn't call Pyroar a hero, but i'd call it noble, while i'd call Infernape a hero as it's connected to Sun Wukong, but I wouldn't call it noble. I'd call something like Scrafty or Machamp Fighting-type because they're neither noble or heroic, they just fights. I'd call lucario a Hero-Fighting, because it's a fighter with connections to common Anime heroes. Sacred Sword seems more like a noble-type, while Secret Sword seems more hero-type. The main problem I see is with the swords of justice, with them being likely to all become noble-hero type, which would make them less unique. You understand what I'm getting at?
