I received iron fist inquisition upon starting as intended. I tried with a couple of the factions and found out I wasn't unlocking the decks. As a pretty new player, i'd like to see myself have those runes so I got a base to work with.
Have you completed the Faction Training missions prior to the Beta. Were the missions showing up with the green check-mark?
All of them but the ironfist inquisition have a green check mark. Tried doing ironfist and it gave me the deck.
That means it is functioning as intended. When we phase out the old game client and the Public Decks this will be addressed.
