My concern was mostly with just how powerful the Tector actually is if used properly in ICW, although I suppose replacing the ISD-II with it might make it more acceptable.
I actually like the idea of having the Tector instead of the ISD-II.
I don't think I really want the Praetor in, since the Rebels will be outgunned enough as-is, and the Praetor is one of the most powerful units in the mod when used correctly even against Era 5 stuff, so yeah. Plus, it was barely ever used during the GCW outside of Shadow Hand. I feel similarly about the Tector, the only reason it really even exists is because of a 2 second shot of an ISD without a hangar. I love the ship in ICW, but I don't really feel like it would fit in very well in this time-frame.
Without the MC80B, I think the Rebels will be pretty screwed unless you add in something, like say, the Dauntless. You could also add in the MC80 Home One type, which would be fairly easy since it's already in the game, just not a a standard buildable ship. I know, I know, it's actually pretty weak for its size based on official stats, but you could always handwave it by giving it stronger shields or something to allow it to tank fire more effectively even if it can't hit very hard. Come to think of it, you could probably bump down the Liberty type to 3 pop. It would still be a thoroughly useless ship, but at least we wouldn't be pretending it's a capital ship anymore.
I'd like to see Mara Jade make an appearance as an imperial hero, maybe even with the hilarious and awesome bug of her having a ranged lightsaber still intact?
Also, if you do want to take a shot at including Black Sun, they could be a warlord type faction, or maybe have some raid fleets. I guess you could also make them playable, but we already have like 5 factions in the game anyway, even if one of them is ultimately really minor, so that might be pushing it, plus it'd probably be too much work. I know the ZC left a bad taste in everyone's mouth, but a criminal faction isn't impossible to balance, I thought AotR did it pretty well with their Black Sun faction. They had corruption, and virtually limitless credits, but they balanced it out with it being hard to maintain corruption and giving them really crappy, old, black market units in space.
Can the rebels get the t-1b tankYes please read the Manual or play the game. It's really annoying when people clog up the forums with questions like this.
As I recall the CSA was pretty much left to itself, save for when Zsinj took it over shortly before his own death, then it went back to it'd own autonomy.
