Perhaps I'm missing something, but how does this differ from the normal LN in game other than just being focused on fighters? I certainly don't see enough differences to justify getting your own ID. Sure, coming from an atmospheric force is a nice back-story, but that has no actual bearing in the game since there's no atmospheric combat...
Also, I'm sure any pirate characters are happy to know that you'll ignore them. That's exactly what Liberty needs, more Navy people who ignore the real threat to Liberty...
