I like HO's, because if the person your fighting against (me) has an idea of what they're doing, it puts you at a big disadvantage. They also result in both planes taking damage most of the time.
Overall, HO'ing is a bad decision, and shows a lack of skill, because if you had skill you'd realize that it was a bad decision.
So when I see someone try to HO me, I think "sweet, this should be easy."
