First of all, I don't bnz tactics or planes would exist at all online if planes met co-alt in MA, saluted each other, and fought 1v1 to the finish with no outside interlopers. You'd have to be out of your mind to up something like a Mustang or a Dora in this situation.
Being a bnz tard starts to look like an attractive option only after you realize how full the MA is of gang-pick tards and how little chance of finishing a "fair" fight you have.
Further, If one is having a problem with runners, there is a simple solution.
Fly a faster plane.
The reason why people whine about runners instead of going with this simple expedient is that faster planes tend to be either harder to manuever (P-51, Dora, Typh, P47N) than your Spit-N1K-Hurri crowd, cost perk points (F4U-4, Spit14), or both (Tempest, 262). Occasionally, when I've had cranial trauma and think t'n'b fighting will be a good idea in the gang-pick fest that is the MA, I'll take up a Hurri. You don't hear me complaining because everything else will invariably try to run if I latch onto their six. That is because not running in that situation would be S-T-U-P-I-D. Not brave, not (sports)manly, nor worthy of a <salute> and well-met, no, just plain old garden-variety idiotic. Although I find those who run away and come back to harass more than a couple of times, vexing. For Pete's sake, if you have to run twice, stay runned off. You go look for a target with less SA, and I'll go look for one stupid enough to turn with a Hurri.
