I don't know about the rest of you, but I don't need a fight to be completely even to have fun. However, when it starts to be one sided with 3-4 all targeting a single bandit (or vulching when there are airborne bandits), I go elsewhere, no matter the side that I'm on. Sometimes I log off completely. I haven't bothered to fly in the main arena for a while now because almost all the fights are one sided steam rolling, and there seems to only be a choice between being in the horde or getting hoarded.
What's fundamentally misunderstood is that if you like air combat, ganging/vulching is against your own self-interest, because it will cause the opposition to move elsewhere. The last time I was in the arena I complained at a guy who was vulching when there were enemy in the air to fight. Naturally, I got the "when you pay my $15" response, and within 30 seconds all of the enemy who had been fighting in the air were in Wirbelwinds: fight over.
