Imo it doesn't even matter if it was a HO or not, HO is just a word with a very short sighted definition. The fact of the matter is, is that you had first guns by a large margin and DMGOD saw this. Instead of maneuvering away from your guns and attempting to set up a reverse or rope, he continued to pull directly at your nose, forcing a ~front quarter shot. I will shoot here EVERY single time as long as I do not think he can get nose full around for the front end ram. Is it a HO? Technically yes but in my book it's called a Free HO, because I am not risking anything on the shot, because DMGod never can get guns on you. The entire premise of why a HO is dweeby is because you are taking a 50/50 gambit of living or dying. In this scenario you are taking 0% chance of dying, so why not shoot? That's my take on it anyways. The caveat to this however is knowing when to stick in line for the shot and when to break away from the shot, based on if he is going to get nose fully around to you. This simply comes with experience and is based on plane, speed, and distance.
