Fighting on the deck is great fun and you can find that all the time quickly and easily. Fighting at mid alt (15K) is great fun and only a bit more of a challenge to find and you find them less often. Fighting at high alt (25k plus) is few and far between especially because many of them dive away after just one turn. I'm always looking for a high fight and probably 50% of my engagements are against bombers when I would just as soon they were fighters. All of this is fun, but the high altitude fights cost more in terms of time and patience. Fighting at alt is certainly a different skill set as you all know planes perform quite different when near their maximum ceiling. That's what's great about the game. You can do so many different things in an aircraft.
I have no problem fighting on the deck, as I said it's great fun, I'm just not going to start there. If you don't want to take the time and climb, no problem. Just fly under me and I will come down to you
This is possibly what was meant by a quality fight BnZ.
