Please take a look at this list and see where improvements could be made.
I would like to keep Vader and Palp, all other upgrades are up for suggestion!

(35) Tie Advanced - Darth Vader (29)

• VI - (1)
• EU - (4)
• Title - (0)
• ATC - (1)

(65) Decimator - Rear Admiral Chiraneau (46)

• VI - (1)
• Seismic Charges - (2)
• EU - (4)
• Palp - (8)
• Merc CoPilot - (2)
• Title - (2)

As you can see, I'm looking to deal big hit crits on every attack. Looking to make short work of small ships and cripple the bigger ones before they can take out RAC and Palp.

Thanks.
I also have every expansion and then some so every card is in play.

I've been running Rule of Two for about a year and that version that you just posted is very close to the version I think is strongest in the current meta. My adjustments to it are to drop VI on Vader to Adaptability (gain 1pt), then swap Merc CoPilot for Rebel Captive (spend 1pt).

You can see my blathering on about it in this thread: https://community.fantasyflightgames.com/topic/229086-is-rac-and-whisper-still-viable/?p=2401914
