See, it's not that they're unwilling to do it...they just haven't gotten around to figuring out how to milk the $$$ from it. I built some Outriders for someone. They're actually really nice. Just don't expect them to steer well...because they're not meant to. The Invader is...questionable. Apparently, it was originally envisioned to have Chapter Serfs on it but someone thought it would provide confusion and people would think it was Imperial Guard, not Marines, for the units.
