So you never engage in a furball?
No, quite the opposite really, but I rarely did, and that was really only because I was with the squad. I was almost always on the side of the 'furball' looking for a lone con, or atleast a 2v1. Why? Because a furball doesn't have the slightest semblance of a true dogfight. Furballs are often disproportionate in their numbers, and this lopsidedness increases (IMHO) 99 percent of the time as the furball moves towards one base or the other (eventually devolving into a vulch most of the time), which makes sense. It doesn't require being knowledgeable or skilled in ACM, and pitting yourself and your plane against the other guy and his, but rather staying fast/ and or high, and having either a strong gun package or be a good shot, and staying more towards 'your' side of the mess. You can't deny this. Try to have a fight with a con in the middle of a furball, and see what happens... and no, it doesn't have to be an angles/ stall fight either.
Furballs promote ganging and picking; that's how one is successful in a furball. Granted one could argue that there's no such thing as picking in a furball, and he/she may or may not be right, but in the traditional sense, it still is picking. Ganging goes hand in hand with the uneven numbers you see in your typical furball.
Look, I'm not saying furballing is wrong in anyway, many folks enjoy it, just like base talking, and that's fine, it's their money they can do what they like. In fact, I in a way need furballs, because I know that's where bad guys are when I see one and I can then head off in that general direction but way off to the side and hope to find a con by himself on his way to the furball and hopefully get a fight out of him. But it's always kind of made me mad and

when people 'bash' (for a lack of a better work right now) base takers who hoard for the capture as detrimental to game play (by game play they suggest dog fighting/ learning how to fight by yourself against another guy, etc, etc) and then suggest that furballing is the way to go, and that by furballing they will rise above being someone who just joins large missions and overwhelms undefended bases, and become great (dog) fighters. In my experiences, this is no where close to being true.
Most WWII air combat were NOT 1 vs 1, but multiple planes furballing
Ok, on to this one, which I'm still confused about, as I have no idea how this is relevant and why you included it in your reply. My best guess is that your using history as a way of supporting furballing. Is this right? If so, what's so historical about Mustangs fighting Mustangs, F4U's shooting Spits, etc, etc. The only history that's really brought into the game in the actual planes/vehicles/boats themselves and their respective FM, and the equivalent for vehicles/boats. Just because furballs where what you were most likely to find in WWII doesn't mean it's the best thing for everyone in this game. Besides, like HT's said, this isn't supposed to be a World War II sim, it's a flight sim.
