I have been playing quest mode now since it was fixed and all of my characters are now level 15. The problem is that I am fighting level 2 content but I cannot find a single card that is not a B or C card. Also I have played the adventure mode with 13 parties and I am still missing a ton of level 1 and level 2 cards including some things like Fortified Armor, Shadow Chain, Flaming Shortbow, Lucerne Hammer, and many others (and that's just the level 1 stuff). Does anyone know if these issues have been discussed before or can provide information on what I am missing?

You start to get deck 1 boons at level 20.

Lots of posts including dev responses here. http://forums.obsidian.net/topic/86762-quest-mode-decks-availability-and-character-progression-til-card-role-selection/

 

In short 1 @ 20, 2 @ 30, if you see cards from 1 or 2 earlier it's because they are balance tweaks with the card and have been moved.  

If you haven't found a card yet and think you should have it's been moved.

Father Zanthus + staff of healing are deck 2 (level 30)

augury and mastework tools are deck C and will not be present unless you've purchased the character add on pack.
