If you could which stats in the current game would you change? Anything from points, upgradeslots, dice, shields...
To be honest I would change the Antisquadron dice of the Y-Wings to triple blue (or 2 blue 1 red) and the point costs to 11, just because it is a fighter bomber after all and was the main multipurpose fighter of the rebellion before they got the X-Wing, that has a quite impressive armament (2 Laser/2 Ion) (and because it was my favorite craft in the X-Wing games, in which I even shot down 52 TIE-Int in a single mission with an Y-Wing)
And I would push the TIE-Bombers by giving them 1 black 1 blue Anti-Squadron (Pushing the average damage from 0,75 to 1,25 (3 blue: 1,5)), because while they are dedicated small bombers, they are still agile craft (on par with an X-Wing) that pose a serious threat to fighters due to their massive ordonance armament. Perhaps they also need a push to 10 Points also then.
