The Sith Lord was once the premiere elite pilot and the face of the Empire. Although he's been overtaken in overall efficiency by The Inquisitor however, this doesn't decrease his potency at all.
With access to two actions per turn it is easy to gain a target lock and pour the hurt into the enemy. He hates being stressed however, and that is a great way to shut him down for a turn or two as with the hard 1-turns, the TIE Advanced can struggle to stick to an opponents tail. Predator is ideal for ensuring you don't need to spend the target lock to modify dice but as per usual, the upgrade costs stack up rather quickly.
Veteran Instincts and Adaptability are of course usual suspects in terms of gaining a pilot skill that will be largely unmatched.
With Engine Upgrade equipped, Vader is capable of making impressive moves up a flank, barrel rolling, and then boosting.
