While I love this game two-handed, I've found going back to older quests becomes almost too easy with newer card synergies. (Tried Escape from Dol Guldur the other night with my 2 latest decks and didn't even break a sweat.) So I'm starting to look at Nightmare mode options.
I've bought 2 for a couple of past quests that are far too easy (Emyn Muil and Dead Marshes) but I'm looking to maybe get a few more. I looked through this guide, but it's dated now, with 2 more years of content now out...

So I'm wondering, is there an overall user rankings of the quests somewhere (outside of the "official" joke FFG rankings) to gauge the best Nightmare mode candidates? I seem to remember Amon Din was pretty easy... and maybe Across the Ettenmoors? I don't know. My memory is foggy so I'll take any thoughts.
