I got thinking earlier (dangerous I know) with the introduction of R8 and soon to be R9 the bar is being raised again and again. This means that all ships that have pilots, including capitals will have increased crew power.
Crew Power is basically the only way to increase a ships capability once the skills, stars and level are maxed out (which is fairly simple to do in most cases).
Unpiloted ships such as the bombers for each faction however do not have crews and thus no crew power. While all the other ships will see some increases in stats with more and more R8s appearing and soon to be R9s, are these unpiloted ships now being left behind more and more?
