I wanted to suggest adding JH Vanguard BOFFs to the Zen store, sold separately from the Gamma Quadrant expansion pack. Given the value of these, I believe players (myself included) would happily purchase these if they were sold separately, especially considering how expensive the expansion pack is and the relative value of what you get in there just isn't worth the money, imo (I wouldn't use any of the ships - I have better ships, and there aren't any Starship traits worth getting from them either).
If you wanted to restrict them to JH captains, that would be fine too, since that's where I'd use them. That way they don't undermine the exclusivity of Superior Romulan Operative BOFFs from fleet Embassy provisions.
Regardless, it would be an easy way to make more cash in your Zen store and give players more reasonable access to these valuable BOFFs.
