Realistically, we're getting 2 copies of Starbird Slash with this Resistance pack, and the Rebel pack will probably come with 2 also. That's 4. If you want enough for 5 or 6 A-wings you have to buy a second copy of one or the other. I don't think this is unreasonable. If there are 3 copies of Starbird Slash in each box, then I would be surprised and grateful.
Look at the spread below. 13 upgrade cards are shown, one of which is a title. It stands to reason that the other 12 cards have duplicates sitting in that face-down pile. I'm not worried in the slightest.
If the argument boils down to the fear that there may be only 1 copy of Starbird Slash in Heralds of Hope, I can't really relate because FFG has shown again and again that they're willing to put extra cards in these bigger packs.
IF I'm wrong, then I will gladly stand by you in despair and disappointment at the marketing choices for this game, @dezzmont . Until that time, I'm going to keep flying casual.
