Why do so many people want to screw up a good thing?
This is what I think. The one trick ponies can't cut it in there so they want a way to get payback on the people that work to attain some knowledge of BFM, and ACM.
I thoroughly enjoy WW1 the way it is. If you want a pure dogfight, be it a 1v1, 2v2, 1v2, or a boiling, churning furball you can find it there. If you want a chance to come out the victor when three bad guys jump you WW1 is it. WW1 doesn't need manned ack for those that can't tell the difference from a yo-yo to an immelmann. The auto ack does a good job of protecting the airfield, and that's all that's really need.
If you are having a hard time fighting in WW1 maybe you're not as uber as you thought, and you might want to think about leaning some ACM.
