I am suggesting a house rule that I plan on testing this afternoon. I plan on implementing it for TIE/ln (Academy Pilot) damage. This is springboarding off the damage suggestion on page 23 of the HotAC rulebook.
Whenever you resolve a critical hit on a TIE/ln (Academy Pilot), instead of drawing a face-up damage card roll a 1d6 and apply the following result:
1: 1 Damage + 1 Ion Token
2: 1 Damage + 1 Stress Token
3: 1 Damage + 1 Stress Token
4: 1 Damage + 1 Stress Token
5: 2 Damage
6: 2 Damage
Justification: Overall this rule will speed up play and eliminate the need to keep track of critical hit cards for the Academy Pilots. The math is loose, but I figure with 7 Direct Hits, 2 Major Explosions, and a smattering of cards that can result in extra damage, 33% chance of 2 damage seems about right. Most of the other cards have an Action to fix the critical hit, which the Academy Pilot will do in lieu of another Action (hence the Stress token). The rest just have an annoying effect that will cause a minor hiccup (an Ion Token).
I will let you all know how it plays out in our test run.
