I hate to post this because it will get nerfed but I suppose....
While watching the very cool battle scenes I noticed that the combat AI seems to concentrate all fire at the largest of my ships until that ship is dead.
Solution? Make one or two of your largest hulls into a dumb target. Put one weapon (sometime the AI ignores it if it doesn't have one gun at least) and then fill the rest up with defense.
Match this up with a bunch of tiny ships that have zero defense and nothing but guns. The AI will sit there and pointlessly hammer away at a ship that it can never hurt while ignoring the small gunship blowing it's fleet to bits. This has to be fixed or combat will become quite pointless and easy for anyone who exploits this.
It takes all the fun out of the combat really. Threat analysis should be the AI's first consideration for firing solutions...
