I find ship AI terrible. Quite often I find enemy squads only calling 1 reinforcement per battle. Sometimes no reinforcements are called.
Slave 1 targeting the only ship that is target locked with proton torpedoes. I see this all of the time.
5's ship targeting the only ship that is target locked with his missle pods rather than applying that target lock on a ship without a target lock.
I don't think I've ever seen an enemy TFP use it's targeting computer ability.
These are just a few examples of awful AI.
