Ok, well that's a different issue. I was just responding to this sentence:
"There have been too many turns where the wingmen get their turn, get to select a target, but no cards appear in the box."
If no cards are appearing in the box, and they should be, that's a bug I have not seen. Although, like I said, this is based on the full version and not the demo. The demo may have a bug.
On the useful cards thing, I think I've seen posted multiple times that the AI doesn't "cheat" in getting better cards, so I'll take Battlefront's word for it. Although sometimes it sure seems like it does!
