But...but what about the players that like the ground attack gameplay?
Myself and I can guess that many players like to attack that incomming vehicle hoard from both the surface and the air.
Seperate dedicated arenas wouldn't give that option if your sugestion were implemented.
With these large maps, IMO, there isn't a good reason not to include areas for all these options within the same arena...with the execption of HTC's vision of how their game is presented to the masses.
IMO, no sugestion is a bad one, some just won't satisfy the wants of the majority of subscribers.
