My gut feeling is that the drive times from some of the flags are going to kill it, unless you moved the mainbases closer to the center. But it also dependes on how (if) you make forward spawning vehicles so that you dont have to drive from the mainbases each time you die. Like the Panzer_Division mainbase, where you have to cross half the map to get to crossroads, wich is the only flag you can attack from it anyway.
edit: i just noticed theres a dirt road going from panzer_div to farm thats not on the map, still thats a hell of a drive, I think I would claw my face off if I drove tank all the way from A8 to B2 and got blown up. I suggest moving the panzer div main flag to B5, to cut down drive time.
edit2: I'm playing a version from 2011-08
