LOL, sure. It's logical to ignore the impact of a vehicle that is only detectable once you're inside lethal range.
Slapshot: That's totally illogical. If the first hit kills your pilot any following hits mean jack squat. It was a single ping kill. I'm talking about flying along a couple thousand feet above the ground and suddenly having a stationary prop and oil, or an instant pilot wound, or half my plane suddenly disappeared and I'm falling to the ground. I'm not talking pilot-kills, which also happen.
That said, Vinkman has a good point. If you limit the rate of fire with realistic reloads, would it even need a perk? I don't know. That might bring it down a notch to the "not perkworthy" level.
Very good observation there, Vink.
