It happens every month. Someone announces that they're ready to quit the game because it's just not like it used to be, and no one will fight 1vs1 in the main arena.
In my experience, I find 1vs1 fights
1. When the darbar is very small for both friend and enemy.
2. I'm in an aircraft with high wingloading.
It's really the second point that's worthy of a tiny discussion. Very few people will hang around for a 1vs1 when you're in one of the best dueling aircraft in the game, e.g. the Spit16. On the other hand, almost everyone is willing to duke it out to the death with you if you're in a P-47 or 190A-8. If you want 1vs1 fights, fly aircraft with performance envelopes similar to these two; you'll rarely see your opponent run away from the fight. Even an F6F is far more likely to have its opponents hang around than a N1K. Therefore, don't fly the first tier aircraft (ENY<10) if you're looking for a 1vs1 fight.
Neurologically, this game triggered dopamine for your brain when you first started to play it. As the years go by, you become desensitized to that pleasure because you've overdone it. Having fun is up to you; blaming others for your lack of enjoyment is probably a sign that it's time to take a long break.
