I've noticed a trend lately that really makes me wonder what the developers reasoning for it is. There are several good ships in the Z-Store, but why not make all of the ships, Ferengi, Cardassian, Jem'Hadar and the new Temporal ships, available through the Z-Store as well? To get the necessary amount of Lobi Crystals from unlocking all of those stupid lockboxes, I could potentially purchase the lifetime membership at it's regular $300 price tag.
The reason I bring this is up that you can purchase spiral wave disruptors in the dilithium store, even though you get those when you are lucky enough to get a Galor-class cruiser. I can understand if it is a new promotional item just fresh out (like the Temporal ships and the Chimera destroyer), wait a while before moving it over to the Z-Store, but there are some players (I believe) that would like the chance to Z-Store the ships and give them a try.
