The Aznable fighter feels really OP, they might not deal as much initial damage up front like bombers but Aznables have such a powerful armament that can't be shot down like a missiles and they're durable and fast enough to deal great damage before they die. If the enemy ship doesn't have any omni shield, the Aznable can do quite a number on their engine as well since they will float around firing their weapons. Most fighters that could deal some damage to ships used a much weaker weapon such as Light Mortars and are often slow. After the 9.0.0 patch, they even gained the Triple Beam Cannon to deal more damage, the Assault Chaingun means they could already do good damage to any ship without omni shields.
I did several solo fight test in the Simulation with no Character Fleetwide Skills, Officers or built in hullmods of a Heron with 3 Aznable Fighters vs an Eagle, Dominator and Onslaught. The Aznable absolutely dumpstered the Eagle and Dominator. The Onslaught didn't die or take heavy damage instantly but the Aznables still managed to deal decent damage and I think the Heron might eventually be able to kill it with enough time. While a solo battle in the Simulation is not a completely accurate test of a real battle since there likely won't be only one ship, it kinda goes the other way too since it means in a real battle you could multiple carrier spam with full Aznable fighters. I think its kinda showing something is way too overtuned with the Aznable fighter. Maybe reduce its speed greatly so its more in tune with other Heavy Fighters that are slow so easy to shoot down or change its weapon completely since other Heavy fighters capable of some damage to larger ships usually use a weaker weapon such as Light Mortars.
