I don't mind the content so much as the packaging. Enough with the boxed sets already! They take up too much room, and besides the Monster Vault this year, I'm not buying any more of them.
I know people have said "Just throw away the boxes" but the "books" inside are flimsy magazine-style things. They aren't even as sturdy as the old BECMI books. The vast majority of original 4E books line up side-by-side on my shelf, but nothing since the first Essentials book stand on the shelf. Everything is in a pile on my desk.
I really try to be positive about the stuff Wizards puts out, but things like this just irritate me. Consistency matters, and starting with big hardcovers, then moving to "digest" style books, then to pamphlets in boxes is anything but consistent. For a company entirely dependent on collector loyalty, Wizards is pretty puzzling in their offerings to those who try to be dedicated to collecting all of their products.
