Don't hate me for loving Gutamaya. I've struggled for a while with a solid role for the Courier though. I think with a tiny tweak it might have a nice niche. I recommend that a second version called the "Imperial Sloop" be introduced. No changes to the model at all, just a consolidation of the 2 3E slots into a single 4E slot. This would allow for outfitting a single 1st class cabin. Now your courier is a badass speedy limo with teeth.
