What about a squad like this?

Jess Pava (28)
T-70 X-Wing (25), R2-F2 (3), Integrated Astromech (0)

Tarn Mison (26)
X-Wing (23), M9-G8 (3), Integrated Astromech (0)

Lothal Rebel (46)
VCX-100 (35), Fire-Control System (2), Twin Laser Turret (6), Hera Syndulla (1), Han Solo (2)

R2-F2 is considered mostly useless because it takes an action, and a focus is usually a

better option. But Jess gets to re-roll her green dice, so 3 green dice with re-roll

should be better than 2 with focus.

Indeed, the results are about 1/2 an evade better, as long as you can reroll both dice.

R2F2 is great for reminding me which page of Neuromancer I'm on. It can also mark pages in other books as well but you get called out for powergaming if you do it too often.

He could be a handy droid on someone like Lonely Luke though.

Luke

Lone Wolf

R2F2

Stealth Device

Now you have four dice to fail, I mean roll, LW gives you a reroll and Luke let's you do a little defensive modding.

Could be okay-ish. Still grunting out an action for that extra die though... Maybe if he was properly supported by someone who begs to be shot?
