Cool. Let's hear your alternate setup idea please (i.e. put up or shut up). Maybe Dawger can help you out. He's great at it. Just ask him, he'll tell ya. 
I think the AvA should have a scheduled rotation published in advance, not weekly ideas recycled randomly.
If this setup was run in February why is it already back in the rotation?
If I was going to create a schedule I would start with the terrains available, separate those into major combat theaters.
Then I would create setups for each theater that progressed from early war to late war.
Then I would create a schedule.
An example...... (Just an example for demonstration)
Four combat theaters with 4 terrains in each
Theaters are PTO, ETO, MED, CBI
Terrains for each theater would be North, South,East,West
Separate the war into four time periods Early, Early Mid, Late Mid, Late
Then just create an event for each combination and run them in a logical fashion.
Week 1 PTO North Early, Week 2 ETO South Early Mid, Week 3 MED East Late Mid, Week 4 CBI West Late
Week 5 PTO South Early Mid, Week 6 ETO East Late Mid, Week 7 MED West Late, Week 8 CBI North Early
In this example every theater would have 16 setups, four theaters would create 48 setups.
Of course real history doesn't fall into neat boxes. As an example a Guadalcanal terrain would only fit into a PTO Early Mid war slot. On the other hand a Europe terrain fits all time slots.
And I know there are tons of existing setups that could be plugged into a rotation like this. I've seen many in the AvA. There are lots of event setups that would be ideal for setups. There is a huge potential existing source for AvA setups.
Long before I sat down and wrote a setup from scratch I would gather as many of the existing setups as possible and use them as is or modify them as necessary to create a schedule that brought the AvA through all the major combat theaters and time periods. Then I would fill the holes in the schedule with newly designed setups, terrains etc.
