That's because that's how it's somehow being classified. More often than not in those two builds I described, Corran and Soontir are in the end game more often than the other ship. And usually they are clutch enough to close out the win. I would go as far as to consider the turrets as the support. They are just a big body guard to these aces. Which plays out exactly like it should.
Because the turret's targeted first because if you don't target it first you can't take it down. And it takes so much effort to take down that Gorc that the Pic has an easy job taking down the stragglers that survived the attack.
