I think part of the problem with Rebel Aces (and it's perception) is that many saw Imperial Aces as a 'fix' to the TIE Interceptor to make it playable. While I think that's only partially true, it's still an expansion. Was the X-Wing put into the Rebel Transport to make it more playable? Why is there backlash against Rebel Aces, but not the X-Wing in the transport? IMO the droids and pilots from the GR75 box are going to be more impactful in the long run then Rebel Aces, and we should stop looking at reprints as purely 'fixes' and expecting them to make all of the past imbalances go away.
There has been backlash against the X-Wing in the transport. Man that droid that gives stress and the flechette torpedo was the doom of the Interceptor and made him useless, Empire was screwed.
But that is so 3 months ago! Now, it's the Rebel Aces time to bring doom.
