Here's the fundemental problem with CVs vs. Land bases. A CV will always retain 100% fuel, it's ord, its ability to spawn gvs and PTs. Land bases, however, can have those things destroyed. Now lets look at the more subtle differences:
Ack: CV seems like hundreds of super fast firing auto ack, 14 manable guns. Airfield, 6 to 9 slower firing auto ack, 3 tops manable guns. So getting to the CV is far harder than getting into the Airfield.
Fuel: CV never has to worry about it. Airfield, a couple of rockets or some intense gun fire, bang down to 25%.
Ord: CV, never has to worry about it. Airfield, nail 2 to 4 bunkers and, well, you get the idea.
GVs: CV never has to worry about it. Airfield, 2000 lbs and its over.
Ok enough is enough. So again, tell me where this great injustice is that requires the CV hardness to be increased. I lost sight of it whilst going through the tremendous advantages the CV has.
