See I disagree, people do show behaviors in Aces High............this is gunna get wierd.
Red dots seem to attract a bigger crowd then just a dar bar. More people up to defend against a cv assualt. People stop upping when you vulch them. Everyone likes to dive on low 262s and follow them around. P51s normally run. N1ks are going to HO. NOE buffs at a furball are normally noobs or 999. If dr7 is on and there is a spawn camp going on hes either on yourside or the other.
Just things Ive noticed over the years.......Im gunna analyze the crap out of this 
Another one I've noticed with myself...
If I get one kill in a sortie, I hang around for more action, given some ammo and fuel.
If I get two kills, I'm more likely to rtb but may still get greedy, given fuel and ammo.
If I get three, I automatically say "paint it blue and ship it through" and head for the nearest green base.
A flashing base is an uppers magnet - even w/o red dots. Why? because - and I project here - the first thing many people do on login is look for a fight.
After all, who wants to do all that boring staging crap when they could be fighting within minutes? There are consequences to this -
Furballs form rapidly.
All but noobs tend to up to these furballs in AC that are well suited to that type of action
Others may bring in other types of ac but they'll do it away from the capped base (seen it, done it... think Temp/d-9/even Typh, Pony, Jug, etc).
As for the furballs themselves, they're usually not true melees but more like a teenage dance; boys on one side, girls on the other, but more like in randomly-forming clusters. Those first forays across the gap are tough.
As for your assertion about the Pony tending to run - I'd further generalize it with Lee's first theorem of AHII:
Given that AHII pilots are rational actors and given that they have perfect information about their aircraft's capability...
AH Pilots will fly their aircraft to its strengths - e.g., fast in a Pony, fast on the deck in a La, turnfighting in a Zeke, etc.
Imj, this leads to a corollary...
The most likely AC encountered in an MA will be one that has a well-defined "best" in some attribute. Those in the middle will tend to get passed over.
This is a generalization but could be supported, by, por example, the turn-rate hierarchy posted elsewhere, speed tables, and the relative frequency of aircraft encountered in the MAs. It's those middle birds that get left out. often. Consider, for example, the P-40. What's it best at? What's the Ki-61 best at? What's the A-5 or G-2 best at?
Okay, refute at will...
