I'm amazed they are adding another 20 cards to the class decks (bringing them up to 50). How they are going to (a) not overwhelm newbies and (b) keep diversity among the characters is beyond me. I hope they can do it.
One good thing about 20 new class cards: there will be more "non-combat" abilities. Right? Please? I hope they aren't just going to add 20 new ways to get extra dice, attrition, and reroll.
