I wonder if it would be possible to have two daily maps. An "off hours" and a "prime time" map, but have these two maps "save" each time they are changed, meaning that if you had captured base 1,2,3 in off hours, and then the map changed to the prime time map, the next day you'd still have control of bases 1,2,3 on the off hours map.
If this were possible you could have small maps in the off hours, larger maps in prime time, and the people who enjoy trying to win the war would still get to do this, and the people who enjoy being able to find a fight would also be able to do this.
It might actually make things more fun for the squads who like to win the war because they could take a screen shot of the map prior to the change and come up with plans or missions for the next day. It would definitely make things more fun for people who play in off hours who want to find something to shoot.
