To add to Baumers idea, you'll end up with dogfights near the end of the fence.
Currently the hardest part I've found is once I have a couple of kills, is trying to get out.
The "ack fence" gives you a chance to do that.
Now, if and only "IF" you eventually wanted more.
Put a barrage balloon near. every ack, the balloon tells you where the ack is going to be. Tie the 2 together, so that if you kill the balloon, you take down the ack for 15 min. Ideally the balloon should be just at the edge of the Acks range. So it "can" be done, especially with 2 or more guys working together. But it isn't easy, or without risk.
So now if they won't come out of the ack, you can take the acks out. You have a point to attack, and defend.
Much like an Aircraft carrier in WWII.
Furballs can and will still happen.
Guys who want more can get more without getting into "win the war" scenarios.
Or without taking anything away from the furball.
