I wouldn't mind seeing strats playing a bigger role in the overall game. At present, it requires too many people to effectively knock them down, they are too far away, and they automatically regenerate after a period of time.
Make them more lucrative targets, force countries to resupply them like a regular base, and you can accomplish the same thing without limiting the use of a particular aircraft.
Perhaps having an overall aircraft factory, one that as its damaged, reduces the availability of planes based on ENY - then you might be on to something. For example, a raid that takes down 25% of the factory, stops the availability of perked rides. 40% takes out ENY 5 aircraft, 50% takes it down to ENY 10 aircraft, and so on.
In theory, it could be an effective way of countering ENY....or not. If one side has bad ENY and the others don't, send a raid to balance the tables for a period of time. Course, this is in lieu of my previous suggestion of having strats stay down until resupplied.
Donning my Kevlar, too....
