Stop counting ack proxies. 90% of kills folks get in manned ack are the AAA killing the plane and the person in the gun simply being the closest to get the kill.
Stop listing the proxy kills to manned ack gunners, and then maybe you can compute kills/hour and kills/death (assuming you give them deaths in the first place).
I want to see a red icon above to manned guns.
They shouldn't get preferential treatment. If they get stats, they need to get all the elements that can HURT stats too.
