In my expereince playing a couple of dozen games on Normal:
In the preious buils it has been concentrating on building 3 types of ship which mostly varried from game-to-game but always included the battleship for Yoral and Fleet carrier for Ashdar
It doesn't matter how many resources the AI has had it was always doing the above - I have been suggesting to have this changed for the same reason: to have more balanced fleets and "force" the AI to produce cruisers for example for its capital ships
Now, with the latest build, the AI seems to be largely doing the same, but I have noticed a couple of other ship types popping up.
Example: In my current game, the Gremak have a fleet of 4 Battleships, 6 Battlecruisers, 1 Escort Cruiser, and 1 Destroyer (also thre are Heavy Crusiers lurking around the map over which I am very hay abouth)
Now if the smaller ships would get slightly more priority, the AI would utilize its resources more effectively and we would get a perfect fleet combinations for our tactical engagements
