This is a thought that occurred to me just recently; I've been quite impressed by the general durability of the auzituck gunship, and the wide firing arc. I wanted to see it in concert with another "tanky" ship that has better than average coverage in the firing arcs.

Below is just a first draft: it seems pretty tight on points & I've had to make a couple of cuts in areas I didn't really want to cut from.

ARC-170: · Norra Wexley (29)
Predator (3)
· R2-D2 (4)
· Rey (2)
Alliance Overhaul (0)
Auzituck Gunship: · Lowhhrick (28)
Veteran Instincts (1)
Wookiee Commandos (1)
Auzituck Gunship: · Wullffwarro (30)
· Selflessness (1)
Wookiee Commandos (1)
-- TOTAL ------- 100p. --

My hope is that we can brainstorm and refine it a little... feels like it has potential, and it should be very possible to turn it into something really rather good.

(Hopefully without adding biggs; as much as I appreciate Biggs it irks me how often he is the go-to rebel ship of choice for covering anything with high hp and low agility .)

I like your idea of predator, in case Norra rolls a blank, my only worry if if someone rushes straight across from her, you'll have 1 focus on Rey, which will not be that useful... hence why I usually prefer her with PTL over predator...

Having two wookies wouldnot be my approach but I don't play that much Rebels.... but here's one with them:

Norra Wexley (29)
Push the Limit (3)
Kyle Katarn (3)
BB-8 (2)
Alliance Overhaul (0)

Lowhhrick (28)
Draw Their Fire (1)
Jan Ors (2)

Wullffwarro (30)
Selflessness (1)
Wookiee Commandos (1)

Total: 100

If you're willing to go one wookie only, which I think might be better you could go like this:

Norra Wexley (29)
Push the Limit (3)
Kyle Katarn (3)
BB-8 (2)
Alliance Overhaul (0)

Lowhhrick (28)
Selflessness (1)
C-3PO (3)
Jan Ors (2)

Jess Pava (25)
M9-G8 (3)
Primed Thrusters (1)
Integrated Astromech (0)

Total: 100

Personally I like this second one, and if you notice you have Jan Ors, BB8, Kyle Katarn gimmick in both, I think it's a great combo because it allows for Norra to have 1 evade, 1 focus and 1 target lock and potentially fully dodge a 3 dice attack. Plus, it makes people really want to go after Lowhhrick, which gives him biggsy characteristics. Jess can also target lock Norra in the second one for help in case of blank. I hope this helps. Good luck!

There is a lot to be improved in your build in my opinion.
Lets start with Norra. Exchange Predator with PTL. Then you take focus and TL either for offence or defence with Norras ability. Secondly exchance Rey with C-3PO for a sure Evade.

Concerning your Wookie gunships Lowhhrick is great with Biggs, but in this build I am not sure how effective he will be. Selflessness on Wullffwarro might be good, but I am not sue. Wookie Commandoes is in my opinion a waste of points. A combination I like on the Wookie gunship is Rage and Inspiring Recruit.

My 5 cents

Here is another odd hodgepodge list I threw together for an Arc and Wookie...just not Wookies...

ARC-170: · Norra Wexley (29)
Push The Limit (3)
· R5-P9 (3)
· Kyle Katarn (3)
Auzituck Gunship: · Lowhhrick (28)
Vectored Thrusters (2)
· Kanan Jarrus (3)
· Jan Ors (2)
X-Wing: · Tarn Mison (23)
· M9-G8 (3)
Integrated Astromech (0)
