Yes, they are way way too good, lol. Let me explain.

I had a game last night. I was invading this guys territory, he was Advent, I was Vasari. He had a ton of bomber wings. So I came prepared.

He had about 40 carriers and a Halycon Cap ship, so lets say 45 bomber squadrons. A lot, I know.

I arrived with 15 squadrons of fighters, and 30!!! Sentinels, the Vasari anti fighter/bomber ship. I was massively upgraded at all levels. I also had the Devastator cap ship with the jam weapons ability (only lvl 2 I admit) and a carrier AE healing my troops. Also another Evacuator cap, but it didn't do much against fighters.

His bombers wiped out about 100 supply worth of heavy cruisers and transports in maybe 30 seconds. All of my fights, and all of my sentinels, did very, very little. Please keep in mind that my fleet was tightly packed, and sentinels were interspersed, so they were constantly firing. I used jam weapons till my cap ran of antimatter. At this point he started hitting my cap ships, and I had to retreat, as my offensive firepower was gone. He never had to engage. My fleet outnumbered his, and was largely anti-fighter.

He did not lose ONE resource, fighters are replaceable for free. There was no time to cross the gravity well and engage his carriers, and he just had them sitting behind 3 armor repair platforms and 10 beam platforms clustered if I had tried.

I really can't understand what I could have done differently. My fleet was DESIGNED to kill a fighter fleet, it would have died against a smaller conventional fleet, and all he had to do was mass carriers to wipe me out from across the grav well. Just carriers and one cap.
