...and other hare-brained ideas:
Trying to find a way to allow defenders to get airborne without eliminating the will to steamroll -err attack. The basic gist of it is to move the fight away from the airfields and to a location where there will be no ack hugging or vulching. The way things are now, the attackers flatten and/or cap the field - eliminating the ability to fight back. The idea of the game is to fight after all, not avoid it.
Here is a common battle ground on the Baltic map:

The spawns allow roughly the same drive to the field as to the town. GVers hate being bombed and will soon be enjoying a reduced icon visibility from the air. With the current spawns, there will be much more sneaking to airfields and vulching. Quid pro quo, I say.
This is my proposal for moving the towns and spawns away from the field:

First, the towns get moved far away enough from the base so there is no base ack covering them. Then friendly and enemy spawns are placed equidistant, on opposite sides of the towns. This makes for a chance to actually fight
in towns, tank to tank.
A few other tidbits:
- Remove all ack from towns and require it to be 100% flat for capture.
- Town buildings stay flat for one hour.
- Increase base ack both in number and lethality to discourage vulching and capping.
- Ord bunkers and radar towers rebuild in 15 minutes. So easy to destroy for a single fighter with great benefit for the attacking side.
By rendering a town defenseless, it will be up to actual players (air and ground) to defend it.
Airfields will be much tougher to cap, which will allow defenders a fighting chance.
Ack huggers can hug, as long as they don't mind you taking their base.
Vulchers can vulch, but will be shredded much quicker in the better ack.
Towns won't be so close to the base and there will be no protection over them except your own countrymen.
Ords and hangars can still be flattened on a base, but it will be much safer done in bombers at altitude.
Capturing the town is the only requirement to take a base. Let's put the fight there.
