Re: Carriers.
I also found it awful that the AI would build tons of carriers, far more than needed to hold its entire fleet of planes. It simply doesn't have a decent AI for carriers (which require a very unique AI to use). I fixed it by setting the flavors of carriers to 1. The AI doesn't build them anymore and instead seems to build a lot more battleships, destroyers, planes, which is all good in my book. I was tempted to just delete the carriers entirely but they don't seem OP in the player's hands, just useless for the AI.
