The cards below are cards that can be played in factions that don't have expansions that include the card, meaning players in that faction will have to buy another faction's expansion to gain access to that card for physical play.
FFG told us before 2.0 came out that players would not have to buy expansions outside their faction to obtain upgrade cards like what happened in 1.0, or rebuy ships they already owned from 1.0 to get new upgrade cards. They have kept their promise with the latter, and despite some hiccups with the initial conversion kits missing cards for their factions (Maul, BT-1, 0-0-0, Barrage Rockets, Moldy Crow title), that was eventually fixed with the card packs.
With the recent geyser of 2.0 expansions, we're seeing a huge influx of cards that are dual-faction or faction neutral that cannot be obtained in expansions for every faction that can play the card.
Luckily, we are currently in a period where owning physical cards is not that important. And I'm sure we're all expecting FFG to announce a second round of card packs with these upgrades in them. However, an unreleased card pack does not fix anything, and we are still in a situation where there is a growing list of upgrade cards that cannot be obtained without buying out-of-faction.
For those that don't play all 7 factions, does the idea of having to buy expansions outside of your faction to get upgrades you want to use bother you? If it doesn't, is that only because you're not playing physical in-person X-Wing so you don't need the physical cards right now anyway? If you needed these cards for tournament or league play and the card pack hasn't come out yet, and you had to buy outside your faction or not be able to play with new potentially critical upgrades, would that bother you?
