Siege frigates- with their ineffectiveness, high cost and high cap space these seem to be just a handicap to the AI after the early game in the original. Yet Entrenchment seems to have added a second specialist siege frigate, for long-range structure attack? The price for the originals might be daunting enough at half the cap space- and while it might be understandable that carrier cruisers have high cap requirements (which could be made higher), historical siege frigates tended to have less crew than regular frigates.
I guess siege frigates could be a bit cheaper without affecting game ballance too much.
Flak frigates- without proper guns these frigates could cost half their current price in the original game, as they have no real function other than to counter strikecraft, which cost nothing, and they take longer to build than regular frigates.
They aren't that bad. While they are no longer the prime mean to kill fighters, they are still useful as an all purpose combat ship. They are though, can dish some damage once upgraded and can target several ships at once while most other ships can only attack one. I do find them useful...
Carrier capitals- has anyone else noticed that siege capitals level quickest and carriers slowest? They could possibly have another squadron at the start, to make them more competitive.
I agree, they need to carry more fighters to make up for their cost.
Marauder- it would be great to have a raider type of capital ship, but the current original game Marauder doesn't have the ability to destroy structures quickly enough after it gets past a blockade- perhaps it could use some dedicated anti-structure weaponry, and maybe even offensive minelaying capacity. Has the expansion made the raider ships more or less valuable?
A dedicated capital ship for structure busting would be great.
More generally with the capitals, the astronomic price of updating logistic support for them might be useful to revise, as it just prevents capitals from being used and I'm not sure why this is desirable? How about a system where there was no extra support cost, but each crew was still trained separately? The screen would then show your 'crew bank' instead of support level. Though you could still buy crews at increasing cost, if you had an L2 capital you could lose a level to make another crew- and Resurrection might be both more effective and easier to implement?
I don't know why people complain capships cost too much... No other ships become more powerful over time and have the same survival rate. They are just not meant to be the all end all type of ships, they need support and escorts.
