1. Increase the required amount of damage for the hangers from 3,000 lbs. to 4,000 lbs., the same as a shore battery.
2. Increase required amount of damage for the ammo bunkers to 1,000 lbs..
3. Increase the required amount of damage for the Cruiser to 4,000 lbs., keep the remaining "other" ships at 2,000 lbs.
Let the debate begin. 
1. Increasing the damage required for Hangers goes beyond "taking down a building" and impacts your ability to defend or capture a base. As an example, while taking out the VH hanger structure is relative straight forward, the tactical impact on the base is significant. The ability of an F6F to take out a hanger structure maybe valid, the ability to totally eliminate GV's at the base is overkill, & in IMHO unrealistic.
Now that I think about it, maybe we need to add an additional VH hanger at all Air Bases and Ports. Of course the simplest thing to do would be increase the damage required.
2. Steel Reinforced concrete structure, penetrated by 50 cal. or 20 mm? Unrealistic.
3. Armor Plated Cruiser going down with the same amount of damage as a Destroyer? Not likely.
Again this is a wishlist, all these wishes would increase participation, increase the potential for more "fights", and provide a better level of realism in both attacks and defenses.
