Oh yeah, I'd like to echo the request for Class 2 shuttlecraft from Voyager. Those were fun looking. The Dauntless is one I hadn't even thought to ask for, but would also be really fun.
More shuttlecraft in general would be good. But then, we also need more shuttle-friendly missions.
I know everyone has been hanging in there for a playable Romulan faction, but I think it would be great if we could make a playable Borg faction - complete with playable ships like spheres, assimilated carriers, and even cubes - complete with missions you get from the Borg Queen. I haven't spend a single red cent on the game so far (only been playing free for the past two months), but would seriously consider dropping some buckage to play as a drone.
And YES, I know you can buy the liberated character already, but it's just not the same, man.
