A company that has three games under its belt and a forth in development is not short on cash so thats a red herring. Most likely cause is simply time and possibly resources, after all a lot of items are created for the C-Store, the monthly episodes suck up a lot of time too I'd bet and thats not counting in day to day running of an online game, patches, future content and the like.
Time however is the single biggest issue, as we all know the KDF was added as a request/after thought. People expected an Empire but got a handful of ships, grind missions and a recoloured UI, now compared to the Federation, it's a caravan compared to a five-star, thirty story hotel. The scales are tipped and will stay as such as the content must move forward with the game, any resources diverted to the KDF will be taken from the alloted resources of the Federation and future projects, namely the Romulan faction.
Hence the lack of ship choices in contrast to the Fed side, and very likely in contrast to the Roms when they are released.
Also, adding Klingon content to the C-Store, especially that vorcha skin, really ticked me off.
I have tried all the C-Store Ships, (except the Gorn one, I think), and can honestly say, the Normal BOP is better than any of them.
The Bre'll is broken. The others don't cloak (so you die in arena faster than your CPU can process).
Ok, the Gurumba is a good ship, but for a tac, the regular BOP is what you need for DPS. Don't be a hero and try the raptor. Once you make that decision, you are already dead.
