Yeah, that's Moggy's fault -- he keeps asking me nicely. Thing is, I think the LDR and WYN don't belong in larger empires at all -- they should really be in mod campaigns where they occupy their own slots. In the meantime, they just clutter the other empires' lists, at least for someone like me who has to go in and check them all to see which ones should be restricted and which ones should be available. Either way, they're nice to have around, but are a pain to use in a campaign that makes sense. There's no good reason for Klingons and Kzinti, for example, to both have WYN ships just because the hulls are the same. It just doesn't fly in D2. Now, for GSA, it is no big deal. Let's just say I'm conflicted about these two races -- they weren't implemented so they could work well within SFC's existing races when Taldren added them in, but they are certainly fun ships to play. It's a campaign designer's problem.
On the other hand, an entire class of ships that all races have is another thing altogether -- there's no confusion about where they belong, just a decision to be made about whether they are worth making available, all things considered.
