HO is a legal tactic, and fairly logical when you can trust your plane's durability and firepower. However, knowing nothing else BUT HOs is definately dweebism beyond compare. Once I've met this N1K2 who tried 6 consecutive HO runs on me. Of course, I didn't walk into it.. first few passes I felt fun, feeling like a Matador, but after the guy's fourth HO attempt, boy does it get boring and lame.
Awarding kills for reckless HO attempts does not help in anyway. The goal of ACM is to kill without being killed, not mutual destruction. You risk a gamble in HOs, and if your wing falls off, no matter what state the guy you shot at is, you lose.
Therefore, I support no kills awarded when both opponents fatally damage each other. Maybe that will actually urge people who rely only on HOs, to learn some other way to achieve kills.
