I would like to see in the end of battle report how many planes I shot down, both with AA and with fighters. Also, there would be nice to see your rewards broken down to see what you got for shooting down those planes.
This would make playing a supportive role more fun and rewarding. As it is now I have no clue if I make any exp or creds for downing planes. And I can't brag about taking out a dozen bombers with my DD in a single mission :D
