I started a mission and a P51 pilot thought it would be good to shoot me down as I took off. The problem with that is that we were on the same team. He kept shooting as I dived off to a side, too, so it was not an accident. Then, after I'd typed several questions that were unanswered, he finally responded to me with "Sorry, I was frustrated from being the low-tier guy for 10 matches in a row." I told him I was going to his squadron about this, and his reply was "Good luck! :-)"
Are there squadrons of teamkillers now?
