I am wondering if FFG has already abandoned the Secrecy mechanism now that the Dwarrowdelf cycle has ended. Neither the Hobbit Saga nor any of the cards we have seen so far from the Númenor cycle have the Secrecy keyword. I can understand it for the Hobbit as this expansion is very much designed to be played with only the Core set. However, it is a disappointment that none of the spoiled Númenor cards have had Secrecy although I believe a couple of the new allies make good candidates.
I think the Secrecy mechanism was a very nice idea that expanded the options for game variations but we have had too few Secrecy cards to really make it work. If they already stop putting any more cards out I doubt Secrecy decks will be used much in the future. So, FFG please do not forget about Secrecy!!
