Dave:
I don't have to imagine it. I've been under such attacks, many, many times
Hmmm...you've noticed something I've noticed. Namely, that 2 or more pilots in b'n'z planes can really frustrate people, even much larger numbers, by keeping them from being able to climb and reach a position where they stand a chance of mounting a counterattack. If you are slowly climbing up, you are slow and alone against them. They'll tend to either shoot you or force you lower in your evasives. Most frustrating. It is also something I think is rather nifty when done well. I have expressed admiration for enemy pilots doing so before, even thought it kind of sucks to be on the bottom.
Even if they don't get a single kill, they tie up large numbers of enemy and keep them from climbing. So basically, it sounds like you are complaining about BnZ tactics because they are frustrating and difficult to counter...
Isn't frustrating the opposition and giving him difficulties kind of the point?
There has been more than one occasion where there was like, a lone pony up high, and someone would say on range, "Darn pony, he should come down and fight!" and I'd say something to the effect of "Yeah. Sure. He should dive down and go to turnfighting my Hurri and the 20 or so Lalas and Spits we got flying around this base. That would be smart." So as you can see, I'm no hypocrite on the matter.
What you might consider is grabbing a wingy and climbing from another base to bounce them. I don't really mind high flyers all that much, I think it is a shame, a crying shame, that the combat in AH is all in the weeds all the time. Always the low alt, always the same group of planes that are "uber" and have the most advantages there, half the time one team or the other is in as much danger from ack as from other fighters, ugh. Up high different planes come into their strength, different feel to the flying, and fights can last longer when there is a lot more of the altitude bank to borrow energy from.
