the vanilla line of civilian craft only for my Xenos, including mk2 upgrades.
It comes down to a personal choice. I think the more different types of ships a faction uses, the less like a faction it looks. The small group of Xenos I fly with will have only one unique pilot while the rest of us look the same. That way the unique one is really unique.
I have to agree here. In the Serpentis we deviate slightly with the occasional use of the Crow and the Civilian Bomber... But, really, aren't they just examples of the Eagle's plump and scrawny cousins?
The Xenos have a perfectly good lineup of ships at their disposal, and perfectly good weapons to shoot. We're not flying the best of the best... But that's really not the point, is it?
