Yep, that's the horse again. There will be just one card in the box. The packaging is streamlined towards campaign, so as not to confuse anyone with instructions to take stuff out of their game on account of specific circumstances.
Just borrow a second card from another player at the event. I can't imagine anyone ever refusing such a request.
The packaging isn't ideal for skirmish, but it's not like it makes for an impassable barrier to play.
1)anyone playing the Bespin Campaign well and truly knows what they are doing by now so confusion about cards to take out is never going to happen.
2) there are already skirmish only upgrades in the big box expansions I.e Targeting Computer attachment so more skirmish only units won't add to confusion.
3) from all the rules I have read so far about campaign none seem to speak of limiting elite units in open groups to 1, (though please point to there rules reference if im wrong) in the case of stormtroopers there is an expac as well and I'm pretty sure you don't need to "win" generic imp or merc units to have them in open groups.
4) pretty sure I'm gonna end up with 2 agent Blaise cards just like all the other duplicate uniques I have so cardstock shouldn't be an issue.
5) Borrowing cards should be a back up not a permanent solution.
At the end of the day it will be what it will be, but it would be nice for FFG to actually show they listen to one of the more prominent issues players have with an aspect of the game that can be solved with 1 more piece of cardboard.
