Does it feel overpowered to you?
Nah, i think not. While it's a though frigate, it's still "just" a frigate. Its utility become limited against bigger ships.
Just played a carrier campaign in Exerelin, unfortunately it was pretty underwhelming.
Glynados are reasonable cannon fodder crafts. I found them slightly inferior to the Talon as their autoguns can't turn like the Talon's turret. Kinda meh as an interceptor as it can't actually intercept things in time. Only interesting if you can spam an outrageous amount of those, assuming you can take down bigger targets faster than their flaks can decimate you.
The Kaivor is much better, not only it's a good interceptor but the Mx4 make it relatively useful against bigger targets. When fielded in mass, their repulsor can protect each other so they can be pretty though to take down.
The Naxos however is the weak point of the Exi fleet. The lancet missile by itself is extremely weak as it can be very easily intercepted. Because of its longer range than the rockets, the bomber always fire it first and it end up wasted against PDs fire or shields. The rockets works better but it still have a hard time breaking enemy shields and heavier armors.
I encountered the Hegemony in Exerelin and as usual they liked fielding capital based fleets of one or two Onslaughts with a bunch of Dominators. But even with more than a dozen wing of Naxos i struggle. The first coordinated wave will always wreak one ship or at least damage it badly but then come the other problem with this bomber.
It need a lot of launch bays to be re-armed, which Exigency lack. The Nasir works okay early game but you can't afford to field a lot of those later one when your logistics points are invested in more bombers. Also the Nasir have very limited utility in combat. The Irithia have the same problem, 2 launch bays are very few for its logistic cost. As such, Bombers can't be resupplied fast enough to attack in swarm and can't break the enemy defenses anymore. One possible solution would be to give it more ammo capacity, enough for two or three bombing run, like the Piranha. That way it will still keep the pressure on the enemy and let the carriers more time to resupply the rest of the fleet.
Exigency works better as a semi carrier fleet. Kaivors are good all around fighters that can keep the enemy shield under pressure while the rest of the fleet, especially the Irithia with its torpedoes can land the killing blow. But as a pure carrier fleet? Not really convinced.
Just thought about a big band torpedo bomber, now that would be much more handy to take down big ships!
Also, nice video Foxer.
