I hate to sound like a broken record, but these topics are all about context and if/when these issues are taken to the extreme.
HOing is not inherently "wrong". But wholesale jousting doesn't really make for all that great of a gaming experience either. The real question is what was the context of the HO? Because sometimes it is the best response for the situation,
but not 100% of the time. Three vs one, and the one gets HOed down, one of those three deserve to get some grief. That's just flat out poor for the guy with that much of an advantage to be unable to manage anything better than a HO shot.
I doubt many people are thrilled to spend 7-8 minutes flying to a fight so the first plane they see can fly straight at them with the trigger mashed down. Sure, that player can do that, but I can also shine a light on it by use of the radio. See? That works both ways. You can silence my radio use, about as well as I can change your tactics....At least a first glance, but being that AH has a social side, you'll either have to address or ignore it

The third option I guess is this merry-go-round which is complaining about the complainers
I once had a fight where HiTech and I HOed each other down (he "won" by the way, because he got my pilot and I only got his wing). What was the context? Well, it wasn't flying straight at each other from 5k separation, with triggers held down from 1.5k distance. He came in on my 6 as I was finishing another plane, and after a quick succession of maneuvers we ended up coming out of opposing turns nose to nose inside of 300 yards separation. (And the result was probably karma since I vulched him about 10 minutes before that

I used HO as an example, but it goes for pretty much any of these topics. A good general rule is that anything taken to the extreme is probably bad for overall gameplay...Including the guys who make it sound like HO/pick/E tactics are taboo 100% of the time, and the guys who say "eff everyone its my $15".
Have to leave it at that for now...
