Loathing: I do not consider that a HO. Limbo was not in position to try to avoid a HO, he was in a position of barely having enough E to continue rolling scissors. You chopped throttle, had gun solution approximately 15 degrees off his nose, and took a shot.
I have guys in the DA who takes 10 degree shots that I consider legitimate. Now, whether they are nice enough not to take that shot is another matter.

It seemed that that your duel was an unfriendly duel. So you are agressively trying to end the fight as you should without hoing and ramming.
In a friendly duel, base on the film I saw and Agent360's screen shots, that is a "marginal" shot that most of us could probably pass up for a more glorious shot (nevermind that could backfire on us

).
