There is that golden moment when you get a fight where your opponent is slightly better. These fights are the ones where you learn the most.
In my experience, those are the fights that last long enough for some picktard to scream in from 20k up and kill one of you.
I just don't see the courtly dueling culture in the MA that is so idolized here. If I get away from the "horde" and go looking for one or two radar cons to fight I inevitably find either buffs, someone completely clueless or AFK, or two guys in Ponies or 109K4s flying around at 25k who'll make B&Z passes until they either kill me or get remotely near the same e level as me at which point they run home. For variety, if I up to defend a field from a lone con I might get a bomb-and-bailer or kamikaze jabo. None of it teaches me anything except to run away as soon as I see multiple cons at much higher alt, because they'll run as soon as I look like I have the slightest chance of getting a non-HO shot in - which I learned within a week of starting.
The other night I was near an enemy base when I noticed all the friendlies had died or run and I was alone with a sky full of red cons. It looked like I could get out if I ran immediately, so I did, and of course four or five chased me. I waited until all but one 109 had peeled off and gotten out of con range and then said, "What the heck, I'll be starting at a positional disadvantage but after all I did come here to fight" and turned back to fight him. It might have been a nice fight, but I never got the chance to find out because naturally after a pass or three a bunch more enemies came back out and killed me. The only lesson I learned from this incident (excluding "I'm not good enough to have the slightest chance of beating or even lasting 30 seconds against 4 or 5 fighters except *maybe* with a huge starting advantage" because I already knew that) is that seeking an "honorable" duel like everyone talks about here just gets me ganged or picked, so don't bother.
The best fights I have all involve the much-maligned base take attempts, because those are the situations where people have lots of motivation to fight without extremely favorable conditions.
