Yes, opting out on your end an scoring as anonymous on the other end seems reasonable!
Or just keep useful data for youself such at hit % etc.
On the serious side. I fly almost every sortie as an attack sortie so I can kill or blow up everything. I'll shoot a plane, a vehicle, a gun, a bomber, a ship, a bunker, a hangar, well you get the picture. This insures the earning of perks for the activity. Not so much worried about the scoring as the perks for the toys when I want to fly them. I do get what you are saying though on the lower arena numbers vs. kills per sortie. Makes sense if you are interested in scoring. Nothing wrong with that pursuit Sir.
