For my own comments on structure and the like, I think it's more Arts compared to Fighters.  Fighters have a fairly limited framework of so many talents and well-defined techniques, related to their rank.  Arts characters have general schools and as many spells as they can get away with.  It's sort of strange to me that we have a comparison of one class/path that's very rigidly defined in what you can have and all based on rank, and a second that doesn't do that.  

I suppose it makes me wonder just how much rank and the like will matter to things, and how/if there's an expectation of character progression and levels like a tabletop RPG.  

As for ranged combat fighters, if guns are out, just go traditional and use a bow.  There's as much room for weird archery tricks as there is gun kata, anyway.
