I have never been in a furball where I did not go in, drag some out or run some enemy down on the periphery away from the maelstrom and get into small engagements. I must have done that 30 times last night alone. You have to work a furball into your favor, with that many willing enemy, you're going to be able to get the kind of fight you want if you put some thought into it.
The people I see who get frustrated in a furball are those that cruise in at a strata inappropriate for the type of fight they are looking for and feel obliged to fight the first con they come across, regardless of the tactical situation, without "setting-up" the fight more to their liking or seeking out bandits more likely to provide "their" fight. Of course even the best laid plans go awry sometimes against human opponents, but that unpredictability is half the charm and allure of this genre.
The red cons aren't the ones that irritate me so much in a furball, it's the green ones. The red ones I can typically choose to engage them or not and fight them how I want assuming I don't get suckered into their hoard.
The green cons on the other hand I can't do much about. It always seems like as soon as you get a con seprated from his hoard 5 green guys show up trying to gangbang some easy kill. The hoard I don't like is typically the green guys hence the reason I almost always go where ever there is a bigger red dar than green.
Nothing ticks me off more than working hard for a kill and setting up that one perfect shot with a single 30mm tatter, only to have 5 green guys come jumping in with their spit16's and Nik2's spraying everything they have at the con I'm fighting. Hence the reason why you often hear me say on squad vox, that I don't want to fly there because there is too much green.
It's also the reason if I am at a furball I typicaly head right past the green hoard and get out there to the danger zone with the red guys.
