That maybe true in the MA's dedalos, but in the AvA there are no perk points to be gained by making kills or "winning the war" and the map doesn't change once the war is won; so other than the chance to say "yeah...the axis or allies won last week" there really isn't much reason for people to fly in the ways you are describing. Granted, that will be more than enough reason for some people to fly high and pick (or other similar methods), but that kind of fighting will always be a by product of a move towards a more strategic gameplay experience in the AvA. A change will have to be made based on the hope that enough people come to the AvA for a chance to experience a "total war" type of play similar to the MA's, minus the garbage that most people whine about in the MA's and that the existing AvA diehards will help promote the growth of the kind of gameplay that this thread is discussing.
Look on the bright side, most of the people who use picking, vulching, HOing, etc are the kind of people who like the easy mode of 6k icons and will probably avoid the AvA like its a psychotic ex, no matter how strategic the gameplay becomes.
