*cough cough cough* Anyone try and capture any of the battlecruisers? In HW: Cataclysym, the first time I encountered a Heavy Cruiser, I captured it. By the time I got to the mission with the Bentusi hypergate, I had a fleet of one dreadnought, three heavy cruisers, two destroyers, three or four tidaan destroyers, a lot of frigiates (both higaraan and somtaaw [no ramming frigates], but no tidaan i think) and and 3 or 4 squads of 10 Acolytes. Then the bentusi killed a whole bunch of my ships...
EDIT: and a carrier. maybe 2 i think. I forget, it was a while ago.
