No offense to the people who worked on the story arcs (myself included) - we did our best to make a silk purse out of a sow's ear. As bad as it is for the Exiles, they are doing better than the Dragons - who were pretty much left out of the 4.86/4.87 story.
There are however, two fundamental strains of Kusari story material that go all the way back to Vanilla: The traditional versus the modern Kusari. From conservatives complaining about the youth of New Tokyo, to the Samura/Kishiro rivalry. In cultural terms, freelancer is chock full of World War 2 allegories, and I can see a contrast between pre-WW2 Imperialist Japan and post-WW2 Democratic Japan.
Of course, if we follow that WW2 allegory to its logical conclusion - perhaps Kusari had not been defeated hard enough by Gallia to warrant such an overwhelming change...Roll it all back to pre-Gallia I say! #joking #notjoking
