Safe crafts?

Are there any KFT legendary cards that are safe to craft right now or is it still too early? I packed DK jaina and gul'dan and Lich King, all the other legendaries I got are trash (lana del rey, keleseth, bolvar) This is the first expansion that I have enough dust to make a competitive deck with, and I can barely wait anymore to get crafting. I have around 6000 dust.
