Lucrehulks
Lucrehulks in particular and the CSA as a whole are being treated as part of Zsinj's Empire, since that's what they were. The PA will no longer be able to capture their planets/build their stuff.
Vengeance
That would be true, Xizer, if the PA still didn't have access to their own buildable SSDs, but the Bellator changes that. The two irreplaceable SSDs was a decent trade-off to start with, however the PA ended up in this position where it ended up being much easier for (especially experienced) players to play, which you can see by looking at the GC ratings we've been asking for on both the forums and ModDB. Making the Vengeance buildable was another part of that which I already wanted to do, but I hadn't actually heard of Sysco before, and I like the idea of splitting it into Jerec as a base hero and Sysco/Vengeance as a recruitable one.
Remnant/Warlord heroes
I have a general idea for how I want to handle this without either gimping them hero-wise or resorting to a b-team roster, which I'll get into later (I'm only 90% sure it'll work how I want it to). In any particular GC where the Warlord faction in question is non-present, the Remnant will keep them as usual (ie, if the PA weren't in Art of War then Kaine would be a normal era 3 hero for the Remnant, to use an example that will never happen). I think it works better as a way to represent all these Imperial groups as incestuous little opportunistic fractures of a formerly-greater whole.
