I think 4.0 is going to delve pretty deeply into the structure of Garlean society; it's going to be our first major jaunt into Garlean territory, until this point pretty much every Garlean we've come across has been military personnel. One would imagine that to sustain an entire city-state however that the Garleans would need merchants, farmers, ect. to sustain themselves (espeically this far from the motherland).

That being said, I don't expect to see a ton of morally upright Garleans; I expect them as a whole to be incredibly pragmatic. And that's okay really, like it or not omelettes require broken eggs.
