Over my last several games I have been experimenting with arming Cargo hulls. Withh 55 points of space, they are the heaviest ships till you get heavy hulls. I've found there are a few plus and minus'...
(+)Largest ship for the first half of the game with 2-3 times the firepower
(+)Able to upgrade any cargo hull, including Colony ships and constructors, into warships at a moments notice.
(+)Nearly invulernable when placed near Military Starbases with buffs
and on the other side...
(-)1 hit point means they can be a paper tiger
This is the most serious drawback i've found so far. On several occasions i've lost a ship even though it's defenses out weighed my enemies attack rating.
I was just wondering if anyone else had tried this strategy, and what experences you've had.
