Well; pretty sure your calculations are right, but what would you need such a destroyer for ? It would be obsolete before it could hit the frontlines
Some free tips, use them or loose them
- Don't build too many useless warships (like the ones above), the maintanance will kill you.
- Buildrate, You only need enough to be able to do 1 turn colonizers on HW on EB, and in 2 turns on normal build on new colonies. Anything more is nice to have but not needed.
- Spend your points on Aggressiveness/Defensiveness, Maintanance and Propulsion Expert. Use the rest to Minerals and Research.
- If you do use organic, get OA III ASAP and Ram your opponent.
And have fun.
