Regarding the interdictors, there are two interdictor makes from the Empire, the in-development stage before/after Yavin, where the forecastle is more differently built (single bridge-like) while the second make ended up having a structure that looked as if it has two bridges on top. I'll give you an example in a few moments. Here it is. The interdictor on the left is the Dominator-Class Interdictor, while the puny "older brother" of it is the Immobilizer-Class Interdictor. http://img.photobucket.com/albums/v520/Kato_Arabel/EmpireAtWar/interdictors.jpg What's so obvious is that the Dominator was designed with slugging in mind to reduce the need for an escort, which is something that its little cousin has always needed. In X-Wing Alliance, with all stats on both at realistic parameters for their class, I pitted both against each other as shown in the picture. Guess who won? Dominator. The Immobilizer died in less than one minute under a full barrage. This should tell you what category the Immobilizer-class Interdictor is in. That's right, it's a freaking CRUISER. Not a capital ship like the VSDII or Impstar Deuce. The Dominator is DEFINITELY a capital ship, think of it as a Victory Deuce with larger gravity well generators strapped on. And yes, the one you see on the right is going to be in EaW, according to the screenshots. Don't start dreaming about Dominator's yet, they were developed around the Battle of Endor, I believe, so they weren't commissioned into common service. Aaand, Paddywhack, the best Imperial/Imperator-Class Star Destroyer in service at the time of the Battle of Yavin would have to be the Imperator II-Class Star Destroyer, or in Reb-speak, Impstar Deuce. And Impstar Deuces aren't available in EaW.
