Thinking about combating the meta is hard right now. Wave 7 opens up so many possibilities but as we are stuck with the current stuff here is the squad I have come up with to combat that issue.
Rear Admiral Chiraneau (46)
Veteran Instincts (1)
Darth Vader (3)
Rebel Captive (3)
Rexler Brath (37)
Veteran Instincts (1)
Autoblaster (5)
Engine Upgrade (4)
Total: 100
Before you all cry wolf over Autoblaster on Rex first consider his Pilot skill and his ability. Against any Mirror build using an interceptor Rexlar can do a great job positioning with his EU, if he can land that range 1 shot without it he can just focus and any hits are going through face up, this leaves RAC to shoot and finish the interceptor pending a bad roll.
They are both PS10 meaning I can choose who takes a rebel captive stress. Also Vess will go through the defense of a falcon, while he might only live 2 or 3 turns once engaged that is enough to do some damage especially if you can flip a few cards face up (chewbacca loose actions or pilot ability? It makes mr Corran much harder to survive as auto damage is getting through and if it's 3, a single vader crit could finish him off.
The defender is also a fast ship and can keep up with most of the other guys as long as he doesn't have to do a 1 or 2 turn.
Honestly I'd like to just have gunner on RAC so I might drop him down to someone cheaper so I can get the points in.
