The Xwing's major weakness is it's durability- I'm trying to patch that with the plentiful damage mitigating astromech slots.
Hobbie 25 (removes stress when spending target locks)
-R4D6 1 (turns damage over 2 into stress)
Tarn 23 (Target locks anyone shooting at her)
-R7 Astromech (can spend a target lock to force attacker to reroll)
Rookie Pilot 21
-R2D2 4 (restore shields on green maneuver)
Rookie Pilot 21
-R5P9 3 (turns unspent focus into restored shields)
