Morfeind,
I thought the DA Furball lake was that part of the old map you are describing put into the updated DA way back when. It could be recreated something along the CraterMA theme but, you would really need to make the three lake airbases uncapturable. Or spiteful late night greifers would keep them captured to deny everyone any chance to use them once they got kester hurt by happy furball monsters giving them beat downs.
Regardless of being bombed, having three uncapturable airfields with three way GV spawns between all of those fields might work. Thinking about it, some genius did a great job with that island with three air bases and all of those GV bases in between. The theme could be expanded with a lake for PT fights and in AH3 there are some excellent villages setup as objects you can randomly lay down before laying down the GV spawns. Something like this the furballers could furbee all night, the GV furballers could join them, and the tool shedders would have the rest of the map to roll unprotected bases to their heart's content.
I know, the toolshedders would get lonely and greif the furballers by keeping their uncapturable airfields shut down all night long. The bomber guys have a lot of control over our game in their single index finger.......
