Well, I'm kind of a newcomer here, but first of all I'd like to thank the authors of TR. The amount of detail and changes is quite impressive and I like the mod a lot more than the original game where the Rebel Alliance just spammend 200 bombers at you and killed infinite numbers of star destroyers -,- .
Regard that, however I have a problem understanding the changes of the smaller IR frigates:
Carrack Class Cruiser, Strike Class Cruiser and Vindicator Frigates are pretty much the same ship with minor differences in cost/pop. In comparison the Carrack is inferior to both the Striker and the Vindicator and even taken the cost/pop in relation just ineffective. Same for the non-Katana Dreadnaught. In 1.3 the Carrack was useful due to its flexibiltiy - ion cannons and turbolasers against frigates, laser cannons vs fighters. Striker vs Vindicator is fine, its essentially fighters + firepower for the Striker vs durability on the Vindicator. The Dreadnaught does essentially the same as the Vindicator or the Striker, just without ion cannons, which seems pointless to me. I'd rather prefer it if the Dreadnaught would lose some turbolasers in exchange for laser cannons, because as it stands now, the IR has a distinctive lack of all purpose frigates and anti-starfighter ships. Defender and Preybirds are nice, but cannot compare to E-Wings or K-Wing Bombers.
In that regard, has something changed abot the Immobilizer? It is extremly expensive now, but still not even as durable as a nebulon b frigate and even though it has amazing anti-starfighter weaponry at least for me it never actually fires them.
