Damage Repair:
An expensive R2 unit that can be discarded to nullify a hit would be interesting. Maybe an R5? Wedge comments that the R5 units make looking behind harder but "then again, you'll take any shots meant for the cockpit, won't you?" in the first X-wing book. So maybe:
R5 Astromech : May be discarded to remove a critical hit with "Pilot" in the title. [2pts]
This would function like the Determination talent card but be available to any ship with an astromech slot AND free up a talent for those who normally use Determination.
Similar astromechs that can be used to fix only 1 type of damage card would be neat. Imagine:
R 5-??: May be discarded to flip "Direct Hit" damage cards face down without being resolved. [5pts]
there already are Damage Repair astromechs.
R5-Astromech: in the X-Wing expansion
During the End phase, you may choose 1 of your faceup Damage cards with the Ship trait and flip it facedown.
It's partial "determination" for ship critis
