You know, I can understand your intentions behind your posts.
But in no way does moving the town further away from a base make vulching more difficult. I couldnt care lesswhere you place the town. But what I am saying is that even if the town was three times further away than it is right now, "CAPing" an air feild is still needed.
Any mission that rolls into a base is going to do three things right off the bat...
1) Drop VH
2) De-ack
3)Drop all other ordinance on town, fighter hangers, bomber hangers, GV's and any other target pertaining to the mission objectives.
These three objectives, which in effect can shut down any or all enemy activity at a base, can be completed regardless of a towns distance from an airfield.
NO MATTER WHAT, when you attack a base with the intention of capture, there will be vulching, there needs to be, and if not vulching than you have to drop the hangers. You can't cut it any other way guys. A town being moved away from the air field has no effect on capture.
