It just needs a tune up like Trinity, probably.
Too many Vehicle Only fields; change some of those to airfields which still allows the treadheads all the same tread-clanking opportunities to fight from the same spawn points and there wouldn't be so much droning around.
Obviously, the V-fields at the bottoms of canyons wouldn't be too sterling as airfields.
Maybe even put in a few more ports and CV groups. Or possibly change some of the "outer ring" streamside fields to ports.
I think either of these changes would up the "action" quotient.
Just my .02.
