It should be.
As for the AI, Ive noticed that in the longer battles, they bring reinforcements into the area they originally hyperspaced into. So if the AI started in the upper right hand corner, they always bring reinforcements in there. It makes it really easy for defense, mainly because you just have to sit there and pick off ships one at a time. The AI doesn't gather strength, it just send ships in one at a time. Don't know if that is fixable, but it's just an observation I've made.
The accuracy values are due for an overhaul. I can make it so that turreted guns miss more often than they do now.
The thing is, I've only been able to use fighters and bombers effectively on strafing runs. In a dogfights, their fixed forward mounted weaponry simply cannot match the swiveled and turreted weaponry on the transports.
Even with flares?
About the fighters, I agree that 1 on 1, Avengers can easily defeat Z-95's. The problem is, the Avenger is far more expensive. Losing such advanced fighters to missiles when, say, E-wings or X-wings would only have taken minor damage is frustrating. As Empire, I hardly ever invest in upgrading the Avenger or Defender because Gammas or Deltas are much safer investments.
They are indeed. Y-wings and something like DX-9s are a pretty nasty combo against some of the tougher transports.
Maybe this is just my experience but high level y-wings can actually be fairly effective against transports, even more so when paired with other fighters (namely x&a wings).
