I'm seeing a lot of different opinions flying around, so I'll chime in with mine.
Here's what I think about the HO:
Historically, it was used in WWII. Now does that make it okay all the time? Well that's what's up for debate.
Now personally, I do not HO unless I'm in the following situations:
- outnumbered, low and slow on the deck while 5+ aircraft continually try to pick me off. In this case ACM can't even be used against any of my targets and the only choice is to take at least one down with me
- flying a P38 (or maybe even a 110), in which the ballistics of the aircraft allow a much farther convergence point past 1,000m, which gives you the ability to at least distract your target (if not kill him or grease him) at farther then 1k without the risk of taking damage yourself (**just to note, I hardly EVER fly the P38 so you will almost never see me doing this**)
- trying to clear a buddy's six if you're coming at him. Sometimes the HO fire (hey I might re-nickname the spit16 that) at his 12 will cause him to break off pursuit of my ally
In all other cases I try to avoid HOs, and usually the 1 or 2 seconds my opponent is using trying to get me in a HO shot are now wasted on his part at attempting a basic ACM for a six lineup. Now I have 1 or 2 extra seconds to begin my ACM for a lineup on his six.
Overall, the point of aerial combat is to nuetralize your opponent, right?
I don't see what's wrong with using tactics that allow you to do this, but ONLY if you put your own safety and your plane's safety first.
It's for this very reason I'll never even attempt a HO in anything that has a convergeance point of less then 1,000m, because at that point it's a 50/50 scenerio...who will get the lucky shot first?
Not to mention that even if you manage to not get hit, 9 out of 10 times you're going to collide with the other aircraft, and that's just the sign of a noob pilot.
The only time you should be colliding with aircraft is from any direction but your 12 o'clock, in which case you didn't see the other aircraft (I find most of my collisions are from aircraft smacking into me from my low 6 during ACM or if they tried to BmZ but botched it).
Bottom line, you should only be using tactics to kill your opponent that require you to put your own safety first.
Unfortunately, this game allows for unlimited life so the dweebs don't care if they ram someone on a HO. (I'm hoping CT, if it's ever released...will change the way combat is executed)
