So I've been tinkering with a list that utilizes an ARC-170 with a Weapons Engineer and M9-G8 combo. The first list I came up with was Norra/Poe(9)/Rex, which definitely seems fun. Doing a little more thinking and reading I'm now debating giving this list a run. Any feedback would be appreciated. Thanks!

Pathfinder Group (100)
Bodhi Rook — U-Wing 25
Fire-Control System 2
"Chopper" 0
Hera Syndulla 1
Pivot Wing 0
Ship Total: 28

Shara Bey — ARC-170 28
Push the Limit 3
Weapons Engineer 3
M9-G8 3
Alliance Overhaul 0
Ship Total: 37

Ello Asty — T-70 X-Wing 30
Predator 3
R7 Astromech 2
Integrated Astromech 0
Ship Total: 35

Bonus: this is the first list that I was considering Squad Link
