Vader not overly popular in the big bad world at the moment but about 45% of my local players fly only Empire. It probably depends on the rest of the list but I need to be ready for Vader.
Option 1: A stress-free, two action, PS4 blocker could cause all kinds of trouble.
Option 2: If you outbid Vader, take the PS9 to move last and never let him get a shot on you.
