Rise of Shadows Crafting

I am looking for crafting advice on a few seemingly "necessary" legendaries from Rise:
Chef Nomi
Archivist Elysiana
I'm stuck because I have accumulated a ton of dust, but I am also trying to "gold out" all of my Warlock cards, since I'm a Warlock main.  Are either of these really worth crafting in the current meta?  It seems that both have their places in decks, but I'm continually seeing their places being rotated in and out of decks.  Thoughts?

Archivist Elysiana is pretty much required for control warrior and control shaman, and arguably for bomb warrior too. Without that card the former two decks would lose all mirror matches due to hitting fatigue a lot faster.

Chef Nomi only really sees play in some tempo rogue lists and nomi priest (which isn't a good deck). 

Neither of them are must-crafts unless you want to play warrior or contorl shaman, I'd say.

I think a lot of bomb warrior decks are leaving out Archivist Elysiana in favour of a more mid-range approach.

The bottom line is that it depends on what deck you're build.
