that isn't what i was think. in addition, while they are all SSDs, i was think about spreading their roles out
in regards to the NR SSDs, i was think it would line up like this:
Lusankya/Guardian: massive bastion of Firepower, with between 12-18 squadrons. 30 pop
Viscount: lessened firepower, higher shields/armor and more hangars, with up to 24+ squadrons. 33 pop
Mediator: Star Destroyer hunter/Self sufficient patrol vessel, with 16 squadrons: 16 pop
then, because there are no NR battlecruisers, it goes to
Endurance: 7 pop, is carrier with 12+ squadrons
Nebula: 4 pop, is advanced destroyer, but has less fighters
Republic: slightly weaker Nebula
and, the Mon Cals:
Home One Type: earlier heavy capital ship, comparible(i think?) to ISD 2
MC90: better version of liberty
and the other two
by comparison, the imperial factions all have a 8-12 pop battlecruiser to tie the SDs to the SSDs
since i'm on empire, here would be their list
Executor: massive, standard SSD, 12-18 squadrons. 30 pop
Vengeance: slightly less powerful, little cheaper, comes with long-range weapons to keep the balance, and to strike from farther away. 12 squadrons. 29 pop
sovereign: Siege Dreadnought: superlaer, plus some concussion missiles, and a few turbolasers, but the rest of the armament would be defense. 36 squadrons. 32 pop
Eclipse: buffed up Sovereign, with more offensive weapons. 58 squadrons. 36 pop
Bellator: half an Executor. with 50% firepower, armor, shields, and hangars, it is a cheaper SSD
as for mediator, it would be at earliest a Era 4 warship, though more likely an era 5 warship, meant to tie down choke points and be a defense warship, though can also double as a Task force leader
for my second suggestion, i said build the NR membership structure, but that isn't necessary. the core tech, as i imagine it, would be at Era 1
X-Wing, Y-wing, A-wing, CR-90, Marauder Corvette, Nebulon B, MC80 Liberty, and another capital ship. supplemented by local Fighters, Corvettes, Frigates, Cruisers, and Capital ships. the core tech would advance as the eras went on as well, with the old stuff(Marauders, Libertys, Nebulon-Bs, and Y-wing) and would be replaced with the MC90, Nebula, Endurance, E-wing, K-wing, and others
as for indigenous units, the Mon Cal cruisers, at leat the smaller ones and Mediator would be a bit more Wide spread then Mon Cal, with mediator(if added) being Core tech. so, in the Mon Cal region, you would find more vessels as well.
i thought of adding this idea more when you mentioned that the Hapes stuff for ASC 1.2 would be added back into ICW, and this way you would be able, as the NR, to use them as well(though maybe not for playstyle/they should have all the same stuff reasons)
but, also, i wanted to here others thoughts on this as well
