The same was true in EaW original...I have only seen the Zann Consortium build a Keldabe battleship once. Other than that, the only capital ships I am faced with are heroes...and the Empire never techs up to get Vader. Very disappointing, but at least the AI doesn't seem to build massive fleets of TIE Scouts any more.
Location: the captain's quarters on board Lusankya
I have v1.0.4 and the Empire and Rebellion double team me with 8 Star Destroyer's (not including the heroes) or a bunch of Mon Cal cruisers. Then, and ONLY then do they both throw in 3 (Read it! THREE) SuperStarDestroyers.
