Ok so i finished my carrier campaign and... Still don't find use for the longbow. Wasting precious fleet logistic, money and supply for a mediocre shield breaker isn't worth it in my opinion unless you are fighting some modded faction with overly powerful shields (like P9 and Purifiers.) But other than this, nope, better investing into actual bombers.
The Trident is better but still inferior to the Dagger. The main problem come from the Atropos that is very easy to intercepted, one flak shot is usually enough to take both down as they are fired close to each other. I didn't really noticed the additional sabot on the Trident but i didn't have the occasion to fight enemies with very powerful shields and when i did, i just overwhelmed their defense with swarm of fighters.
The Atropos seems flawed in my opinion. Maybe replacing them with reapers will give better results?
I also tried to spam Wasps in my fleet, didn't worked out very well. Then again, they are interceptors and that's the only job they can properly fill. I usually prefer the Talon as a cannon fodder fighter, the hard flux produced by the Vulcan is very good.
Piranhas are pretty scary now, it's maybe because i encounter more of them but i think they are definitely more viable. They tend to bypass enemy shields by dropping their loadout when they fly over the ship, my Tarsus freighter remember it.
Mining drones are still worthless but can tank an absurd amount of firepower. Not sure if it was needed as they're not really supposed to be used in battle anyway.
Xyphos were already pretty good, they usually seems worthless because they're alone. When massed, they become really scary.
The Warthog speed boost is very good, it badly needed it. Not sure about the Gladius buff as it was already one of big boys with the Thunder, didn't tried that much though.
The Condor is still vastly inferior to the Gemini. Its rival have more OP, better mounts and PD drones.
