Kell scored a zero for one sim, not for all of them. Briefly (I can respond more at length tomorrow), but Vindoo was hardly an imperial die hard as I understand it. He was a hero of the clone wars and a recruiter for the Imps, but he never flew in combat for them. As for cohesion...meh. Overrated. Certain combos, sure- Corran and Ooryl, for example- but outside of wingpairs its less useful than we tend to credit it too. Like, yeah, Ooryl and Face were on the ship at the same time, but their experience together isn't such that they are naturally a better pair than Falynn and Tycho. I posted a hierarchy of cohesion years ago, but really if the pilots aren't wingmates and if they aren't going to immediately murder each other, its not so important in my mind.
