The object here is to move the conflict zone to places between airfields rather than over air fields.
Essentially the land grab routes are via vehicle fields. Some vehicle fields give access to the towns which must be captured to secure an enemy air field.
Air fields only have remote gv spawns to their respective towns.
The reader will note that the towns are mainly behind the airfields such that the "front line" has already passed the airfield before it is vulnerable to capture.
Each country has 3 zones. In the central zone the strat facilities are in the rear with the HQ. In the two outer zones the strat is scattered.....somtimes close to air fields to provide additional AA coverage.
All ports have an associated fleet.
I have put a grid in reference although it may need some modification re size.
Buffs have loads of targets to promote the land grab
Vehicle fields, strat, fleets, towns even some bridges at the country start borders. But little is now served bombing air fields (with the possible exception of VH's and troop porkage)
Capping air field and town with the same force (ie capping town and vulching air field) is also no longer viable. Vulch fests no longer aid capture.
No vehicles can gain easy access to attack airfields. (only their towns)
Capturing a town without taking the local vehicle field will result in the loss of the said airfield shortly after. (given normal game balance)
Radar range should over lap to provide 100% coverage over the main land.
Landscape (hills and valleys etc) would be such as to focus ground combat.
