The damage deck has been unchanged since the beginning. 33 cards, 7 direct hits, 2 of each other card.
Only EPT's and secondary weapons are at risk.
But since then we've been given system upgrades, crew upgrades, modifications galore, and noone can hurt an astromech which can be as strong as any EPT.
Is the damage deck too limited in scope? What kind of damage cards might be useful to add?
Barring all logistics of getting an upgraded deck to all competitive players (casuals wouldn't matter too much) of course, that is a nightmare in and of itself unless FFG would release a free app or something.
Personally, I wouldn't mind seeing turrets being locked in a primary arc position, or asymmetrical maneuver limits.
