I personally would like to see the AvA room have early to mid war maps with its historical plane set. Most days that I look into AvA it has a tank map up for Thursday tank fights, to whatever night that's on (and that's fine, I have gone to them they are fun) but when they are done you need to put up some type of historic room.
Personally I would say that the AvA should be on the BoB map until player numbers get better. I know that more than one person (myself included) has said that " I would go to Ava if it was ever populated" I think the BoB map is the most liked, and as numbers grow, you can put in a Russian map, or a Pacific map. But last I saw an Allutions map, no bases could be taken or something of such.
AvA rooms should be maps that mud can move. A stale map becomes stahl in the air as well.
That's my 2cents I love AvA I would love to have 50 on 50 or more....
