KoTH this coming weekend! (and I've got to run a .50 cal range for the Reserves......darn it!) Not always 1 v 1, but close, and the challenge of different planes (well, sometimes).
Only place you'll get the 1 v 1 you want on a regular basis is the Dueling Arena, or by conducting training in TA for noobs.
I don't have very good fighter numbers.... guess I don't know when to run. I'll make an attempt to disengage and ditch when I'm seriously pilot wounded, missing various important parts (like a wing), or engine locks up.
But, don't see many good 1 v 1 any more. Don't see very many lead-wing teams either, working well together. Five or 6 all chasing 1 plane.... yeah, that I still see. All firing past one another.
The War Arenas are what you make of them. In LW, I tend to pick a lower sided country and play defense these days. Took a C.205 up the other day to go and defend a CV which got me 3 kills, a few assists, and a crash land on the CV deck. It was some fun. I suppose you could force a fight in EW or MW against someone running a JABO mission, with no horde to run to, and you had the E to keep them from running away.
