I was worried, Nightfallen might be difficult to get. But i changed my mind today why?
After two weeks of release, i got allmost revered with Valajar, Highmountain Tribe, Court Of Farondis, Dreamweavers while with Nightfallen got 2K revered.. While with The Wardens i started honored farm.
Currently Wardens world quests got only with wanted / danger ones, while rest reps got more.
