Some I suppose have forgotten not too long ago the ack fired cyclic into the sky. Just last year this burst thing happened. Deacking a field went from...you WILL die in the attempt to, you actually have a prayer. I think field ack is just fine the way it is. Now, as to accuracy, puffy ack is radar driven...so you have to vary your alt and heading to survive that. fly straight through it, even at range, you will be toast. Accuracy of field ack, yes, I think it is improbable for a field gun to hit a plane 4k away. At the same time I think it improbable a tank 7.5cm wide round can hit a plane in flight from 1k. But, those are just part of the game and you live with it. The ack is now easier than it has been, further reduction in it's effectiveness would just be silly.
As for AKAK.... pfft. He does have a point, he just has no personality or filter.
