I guess this will being out the "nay sayers", but at least look at it with an open mind! I would like to see 2 VH hangars located somewhere on the edge of town. One on one side and the other one on the other side. The reason for this is simple, to slow down the "hordes" and made it a little more difficult to capture a base. Once these hangars were bombed and put out of commsion, they would be down for 20 minutes. It would give the towns more defensive capbiliblty and make it more difficult for 2 people to take a base. In addition, it would give the bombers or fighters, two more targets which should be "killed" to disable the base and town. This would make these hangars a priorty for mission planners and would give the GV people more options than just the spawn point or coming off the base prior to the VH being "killed". Yes, it would make it more difficult to capture a base, but consider the possiblities!
That would do the exact opposite of that you are asking for. It would take more effort to disable and capture a field. More effort easily translates to more aircraft required.
Additionally if you want to slow down the hordes, what is the concern of two people taking a base then?
BTW... If you want to actually disable a field. You take out the VH, and then you take out the field ack. You don't need a horde for this, and you can ignore the hangers other than the VH. The mission planners do not even do this, why do you think they will plan better if you add more targets?
