KD and Hobbit are must for Dwarf heroes mostly.2 Spirit dwarves and 2 Lore dwarves are in that pack.
But for player cards, KD is somewhat weak.
I don't think I use any cards from KD even when building dwarf deck with exception of Erebor Recordkeeper.
With Dain most of them are cherries on top.
As for Hobbit, there are some great player cards, but they can easily be replaced by others and does not play crucial part in any of the decks.
