I was playing against my friend today and I have a lot more capital ships than him so I thought it would be an easy battle but he actually had a ton of small frigates. My fleet had to retreat due to the mass of ships. I was wondering is it better to devote most of your resources to getting more cpaital ships with a smaller amount of frigates, or to devote your resources to having tons of Frigates with maybe a couple of Cpaitals?
