I agree, except about the Hacker Bomber. It makes more sense than a Hacker LF, they'd want their sensitive scanners and all that behind heavy plating and shields, which an LF doesn't quite qualify as to me.
Though I haven't changed my support of most factions having at least one ship that they can claim as their own, even if it's just a modified allied/generic model. I have a hard time believing the Xenos wouldn't modify an Eagle, for example by screwing with the generator to support more weapon power at a reduced shield class.
A lot of people would remark about factions having pride in their technology, to which I say this: Not everyone lets their pride overrule their pragmatism. There will be Outcasts, native and otherwise, who see the use of heavier firepower and armor such as the Loki and Werewolf respectively, and Rogues who appreciate the speed and subtlety (or at least speed:P) afforded by ships like the Falcon or Scimitar. And in-character there shouldn't be anything stopping them from using allied and neutral commercially-available ships. Now, militaries are exceptions to this, as is their nature, but even they could justify utilizing "modified" Eagles with military-grade armor (that is, armor upgrade 8) and military weapons.
For those who say everyone would just use Eagles and other generic ships, I disagree. If someone had their heart set on using six Sabres, they could just as easily make freelancers and mercs, which would also be the better way to go about getting one's PVP fix - military factions outside of Liberty don't have a fight readily available to them as often as mercs, hunters, Outcasts, and Corsairs.
