Are low tech ships supposed to be less power but cheaper? Were do you guys get that from?
One thing is that low-tech ships tend to be valued at fewer DPs. Holds true for frigates, destroyers and sort of cruisers (Dominator is a heavy cruiser, but we don't know how expensive heavy cruiser of another design philosophy would be. Mora, on the other hand, is cheaper indeed). Design philosophy is also skewed this way somewhat; low-tech ships are comparatively worse, but can support one another, while high-tech ships are better, but less numerous, having to use their mobility to achieve local superiority. At least, that's the platonic ideal...
A more significant reason why I brought that up is because Alex made a comment that amounted to that, one day. Though, now that I think about it, it might have been from before maintenance and recovery costs were unified. I never really thought about it since. On one hand, the fact that I could do just fine regardless proves that it's not a big handicap, but on the other, Alex ought to take a look at this and make sure that he didn't accidentally triple the maintenance of certain ships for no good reason.
