Each capturable object is it's own mini battle of capture the flag. Limited to the scope defined by spawns and the willingness of players to fly aircraft. If you can organize the team, you can NOE sneak an airfield next to an enemy HQ and play Ft. Apache for the night. Key concept is "If You Can Organize A Team".
Win the war is just there to give people something larger to accomplish if they want to capture a certain number of flags in a night. The MA in general is 3 countries with about 20-80 capturable flags. Each promoting the possibility of 3x 20-80 ongoing mini battles for 7 days or, until a group can flip the map. Other wise there is no war and no front. Because each base is a mini battle, it gives the localized players the chance to defeat the attacking players ability to express force in a semi controlled manner. Or until they organize a hoard and steam roll everything.
Allowing unlimited range spawning of GV's would make defending anything in our capture the flag centric arena not worth the $14.95. You could never cut off the stream of attackers at their source. Your real wish is rather transparent. Hitech please change the MA into a WWII centric strategic force game.
The AvA is setup for this nonsense, and the CM's are always looking for 2 country centric chess piece war ideas. I doubt Hitech will reprogram the map functions just for the AvA. But, the CMs might listen to the idea of complex spider webs of GV spawn lines from every single base to every other single base. In effect that's what your wish will accomplish in the MA.
