Think dynamic maps that offer new opportunities based on numbers and bases instead of ENY.
How about an overlay feature on our maps.
When a country gets down in bases or players, an overlay is enabled with new spawns from a main base deep into the enemy territory with no perks on GV's. Maybe even allow a few planes to spawn at a captured GV base. These would have great spawns near cities that would require serious resources to defend.
A Battle of the Bulge scenario.
It would be nice if the overlays rotated so that nobody would know what's coming. They could also have a clock factor and go away after 20 minutes.
