I only JUST played bearbaiting with the new Sathanas. Yeah, I know, I'm very late to the party.
I must say though, the mission is fantastically beautiful, and my wingmen actually do something on insane! I presume this is because turret boxes have been fixed. Flak turrets are gone within the first few minutes, and Alpha wing can usually manage to down a beam turret or two all by themselves. I remember with the Retail model, flak turrets are nigh invincible, and every last wingman is good only for drawing fire. The change makes Insane decidedly easier, but far more epic.
Kudos.
