Yeah I have to agree. Some things that Delphi pointed out about the demo was that cost and build time were greatly reduced so that we could play around with all ships. The Empires cheap ships are not that great. I mean Victories and Acclamators dont stike fear into the Rebel hearts or anything. ISD's are really good but are going to be really expensive and so to build which means if the rebels keep raiding planets the empire player will have to spread his forces out thus builing more cheap ships rather than more expensive ISDs. It will balance out fine. Even the Death star will be a real challenge to build and use.
As for the realism aspect, I can see both sides of this. Perhaps they might point it back in as an optional part because its one of those dividing issues some people like to focus on the combat and fleet movements where as others are for the diplomacy.
