There are plenty of "low tier, cheap & dirty" ships in this game, as there should be.
Need fire support but don't have a lot of cash? Buy a Buffalo Mk II.
Need a cheap escort ship or two? Buy a few Talon wings.
Need a cheap all-around boost to your fleet? Buy a Hound.
And, as already stated: Need a cheap flight deck? Buy a Condor.
In my view, these are ships that simply "plug the hole" in your fleet until you can replace them with something more capable. There is nothing wrong with that in my eyes.
Nah, those other ships are more than hole pluggers. Of course there are better alternatives for the overall role they fill, but all of those ships have something that distinguishes them.
The Buffalo MK.2 is
the obnoxious missile spammer and the only destroyer without shields.
The Hound has unmatched mobility and is great at distracting superior enemies.
Talon wings are close to being a poor mans Wasps, but their armor and lower FP still make them different enough.
Only the Condor is really nothing but a worse Gemini, even the FP costs are the same (whatever that will mean for the new deployment system).
The strongpoint of the Condor might as well be it's cheap price and high availability. So while it might not be strong combat-wise, the big advantage shows in the campaign.
Price and availability certainly are important differences, but I don't think its enough to make a ship interesting. I mean, that's basically a given, even the most straightforward and boring weapon upgrade in some shooter still costs more and is available later than weaker versions.
Although, now that the overall number of flight decks in the fleet actually really matters, a cheap flightdeck, available in numbers, might become a selling point with much more importance. Still, I think it's a good idea to make the most of the ships we have.
