I am thinking of running Norra and Miranda in a regen-based list with Biggs to back them up. The problem is that both Norra and Miranda are fairly lean in order to be able to squeeze Biggs in.

39 Norra (29), PTL(3), Tail Gunner (2), R2-D2 (4), Title (0)

35 Miranda (29), TLT (6)

26 Biggs (25), R4-D6 (1), IA (0)

Is it worth it for the protection he offers? Or would I be better off replacing Biggs with someone cheaper in order to get a few more upgrades on the heavy hitters? Miranda could benefit from C-3PO. Homing Missiles and EMs would be nice too. Norra is pretty much optimal but Vectored Thrusters would add some flexibility.

I could run something cheap like a Z-95 or a Prototype A-wing for blocking. Would that leave Norra and Miranda too fragile, even with Regen?

I've run this. It's too fragile for competitive play in my local meta. Too many hard hitting big ships out there. Biggs is good, but whatever is flying with him needs to be able to put serious hurt on a shadowcaster or ghost in the 2 turns of firing he gives typically before blowing up. Best case is 10 damage from Norra and 8 from Miranda. And that's if everything goes right and you're at range 1 with Norra and Miranda, and spending shields from Miranda for the 4 dice range 1 shot.

This is a favorite blocker of mine, only saves 3pts, but it is typically pretty hardy.

Green Squadron Pilot (23) - A-Wing

Push The Limit (3), Chardaan Refit (-2), A-Wing Test Pilot (0), Autothrusters (2), Wired (1)

Not really sure it is the answer you are looking for though.

This is a regen concept I was theory crafting last night, hope to test it this weekend.

Poe Dameron (37) - T-70 X-Wing

Veteran Instincts (1), R5-P9 (3), Autothrusters (2)

Biggs Darklighter (27) - X-Wing

R3-A2 (2), Integrated Astromech (0)

Thane Kyrell (36) - ARC-170

Seismic Torpedo (2), Jan Ors (2), R2-D2 (4), Alliance Overhaul (0), Vectored Thrusters (2)

I've come up with these:

Norra (PTL, R2-D2, Tail Gunner, Alliance Overhaul title)

Miranda (TLT, C-3PO)

Gold (TLT)

100 points

Norra (PTL, R2-D2, Tail Gunner, Alliance Overhaul title, Engine)

Miranda (TLT, C-3PO, Advanced SLAM)

Prototype (Chardaan Refit, Autothrusters)

99 points

Norra (PTL, R2-D2, Tail Gunner, Alliance Overhaul title)

Miranda (TLT, C-3PO)

Green (PTL, Test Pilot, Wired, Chardaan Refit, Autothrusters)

99 points

C-3PO on Miranda makes her last so much longer. As JSwindy wrote, that Green A-Wing can be very tough.

I have toyed with the Norra/Miranda/Gold build as well.

The idea is to stay on the run and hopefully get some nice long range shots in (TLTs are great for that) while regenerating the (hopefully) limited damage that Norra and Miranda will take. The Gold is better than Biggs in this regard since it doesn´t have to face the enemy and you don´t have to stay in formation.

The thing I would worry about is that the ARC is kind of slow (especially if trying to regenerate with R2D2) so it might not be able to run away. Miranda is much better at that because she can slam.
