A.I. Fleets, Ship construction and...

OK, I have been working on a Mod for the past few weeks with a few goals in mind. One of the goals is to get the AI to build different and more diversafied ship sizes in their fleets. (Or Using Lightt Cruisers, Crusiers, and Battleships, instead of just a huge fleet of Dreadnoughts).

I think it could give the game a little more strategy in terms fo fleet battles if they had different ship classes with different abilities.

Also I would like to try and rework how the AI designs it's ships. I think there is a out of room for tactics and strategy if I could fix how they create their ships.
