I'd like to start this thread to get examples of how the AI responds to your ship designs, and if you think it is making the right decisions.
So I was playing a head-to-head game against the Drengin last night (crippling diff), and dragging out the war without capturing any of his planets, just to see how the AI would adapt to my ship designs.
I had a large ship, stats were 9 beam and something like 5 armour, 2 point-defence. This was old tech, but I was holding off deploying more advanced ships to see how the AI would respond.
It built a frigate with 1 beam, 3 missile and 7 shields. Now, maybe I'm crazy, but this seems rather imbalanced to me. Sure, I had a lot of trouble penetrating those shields. It made for longer fights. But I know the AI had decent lasers and missiles. It abandoned further weapons research to push up shields.
I think in designing a ship to counter another, the first priority has be ensuring you can penetrate it's shields often enough. As a rule of thumb, if your attack is less than or equal to their effective defence, you are on the wrong part of the curve.
Also, what's the point of splitting your attack against an opponent who has reasonable defences?
