Capital Ships do not appear to be able to stand up to smaller ships very well. Sure, they can deploy fighters of their own, but they have a massive vulnerability due to the Silhouette differences being used for base difficulty and further their defenses seem based on Armor - which weapons like Proton Torpedoes can punch right through and cause Criticals. Critical Hits will thus kill an ISD way before it hits its HTT. I'm thinking that there needs to be a base Critical Hit modifier for larger ships. Perhaps -10 or even -20 per point of Silhouette above 5? This way it will take several critical hits before massive ships start to fall apart. As it now stands, a dozen X-Wings lining up a shot with proton torpedoes can kill just about any capital ship as long as they can get the two advantages needed for a Critical Hit (and since the shot is only difficulty 1...).
As an alternate, I'd rather see a "Structural Reinforcement" rating for large capital ships. Have this rated like weapon qualities (level 1, level 2, etc.). The rating increases how many Advantages are required to activate a critical hit. So if the ISD had Structural Reinforcement 3, it would take 5 advantages for a proton torpedo to activate a critical hit (assuming it hasn't exceeded the ISD's HTT).
