Yah about the Borg ships. Throughout trek history the Borg never used a massive amount. Certainly not the major fleet sizes that the federation or the dominion would have fielded. I know that it may be to late to do such a major overhaul but why not give it a try? Less ships but much bigger and more powerful. I mean waaaay less ships
The other thing I was thinking about is the inherant values of ship classes like frigates or destroyers, ie 40% harder to hit etc. There is a second value there that is always set to 0 the first value I assume is ship def. Anyhow might be interesting to tinker with those values a bit to add a bit of subtle differences. For instance Dominion ships could sacrafice that % to hit for decreased cost and perhaps slightly less tonnage. They had tonnes of inexpensive moderate sized ships and a few of the Massive dreadnoughts.
Possibly another idea with the borg to go in hand with increased tonnage would be to require more Crew Quarters and perhaps 2 brdiges for lesser classes and 3-5 for more powerful classes. SImulating the incredible redundancy of the Borg.
All in all this looks amazing and i'm beside myself waiting to play it
As I've never played the game take all my suggestions with a grain of salt
