Carriers are quite awesome now. I've used Condors, Drovers, Herons, Moras, and a Legion at some point or another. The Legion is something else. It's like up-sizing a Dominator and adding 4 flight decks. The AI still treats it like a carrier though and doesn't like to really get into close quarters (even with an Aggressive officer). However, in conjunction with its fighters, very little can stand toe-to-toe with it. I've face-tanked an Onslaught and come out on top but the Paragon...I couldn't come close to even hurting it with a Legion. It's in a league of its own right now.
As others have said, a lot of the old ships have had new life breathed into them. Most of this is due to previously overpowered ships being unable to cover all their flaws via skills like vent spam, a ton of extra OP, etc. Hammerheads are much more competitive with Enforcers because of their speed and fighters have been creaming all the Medusas I've been fighting.
I went Hegemony in my first play through but would like to go high-tech next. The Aurora, with the speed ability and the new synergy mount, looks dead-sexy and I really like a lot of the high-tech fighters. I'd love to pair a Paragon with an Astral and see the mayhem.
