Thirded! Demon Knights is my secret favorite New 52 book! That first arc wasn't slow, it was measured! That first arc was long but they managed to fit in some primers on the backstories of like 4 or 5 out of the 7 characters all while building up a foreboding siege, adding betrayal and intrigue, dragosaurs, sorcery and some of the best art in all of comics in 2011.
That book's in the hands of god damned professionals and everybody needs to read it!
Edit:
I wanted to add that while it's more comical fantasy than straight high fantasy, more people need to check out
SKULLKICKERS. I never heard of it until I saw a review for one of its issues on ComicVine so I went and checked out the first trade and it was GREAT! Second trade actually managed to be better. There's really good (if a bit Asian styled for my tastes) art and it's legitimately funny. It has some of the best onomatopoeia you'll see in comics.
