My Five
Push The Limit: This should have been a unique or priced 1 or 2 points higher. I don't mind seeing it on a lone ace, like Soontir; some aces need it to survive.
Engine Upgrade: This should have been +2 or more points for Large ships.
After these two, the rest don't seem so bad.
Twin Laser Turret: I hate to dog-pile on such a newer card, since I haven't gotten to see much of it in play, but it seems too good. It seems like it should have been a K-wing only card, but the HWK could use it to help it out. I also hate to rant about this card because I love Y-wings; this card has helped out the Y-wing so much. Maybe it should have been a single 3-die attack that keeps all results (i.e. not limited damage to 1), with a boost to the attack roll built in (maybe Accuracy Corrector built in?). I feel like the card is a response to PTL+turtled Aces; fix PTL and this card is not needed as much.
Veteran Instincts: Modifying Pilot Skill is fine by me, but this card competes with so many other Elite upgrades that it limits the field. If I were to fix it, I would let any ship in the game increase it's Pilot Skill as part of the game outside of Upgrades. The cost would need to be progressive (i.e. +1 PS for 1, +2 PS for 3, +3 PS for 6).
C-3P0: The mechanic is flavorful, but its impact on the game has been far too influencing. It's fix would be a cost increase, perhaps to 5.
