It also preemptively nerfed the Starwing a little too, so it isn't just the K-Wing.
With the old Adv Slam, you could use it to fire off a Seismic Torp, then fire munitions or cannons (with the titles) after the disabled token. And if you had snap shot, that would be 3 'attacks' a turn!
They weren't just scared of the K-Wing lol
