His ability may only allow him to get proxy kills. Maybe he is a quadroplegic, maybe some other reason. Do not rule that out. Keep an open mind.... it's just a game.
Can't tell if you are being sarcastic, but im just pointing some things out. I find it strange youd want to get proxies but not use a plane that scores kill counts.
Looked at his stats for last few tours, its quite funny. Went 33-4 (6.5 K/D) in a D3A in tour 310. And he went 30 - 11 last tour in a D3A. Only 1 other guy had 1 kill. Hes putting up a better K/D than roughly 70% of the game without even flying

. No damage points at all. So why wouldn't you want to score as attack atleast? In any case, its very hard to understand intentions here and I sort of agree with others that it impacts gameplay in a negative light if its giving away CV locations.
