A buddy of mine and I stopped by our local hobby store today and I glanced at the new 5e Player's Handbook while I was there. Flipping through the spells section of one of the books, I noticed several pages that looked as though the printer was almost out of ink. The lettering, though I could still make out what it said, was faded and streaked severely. On several copies of the 5e PHB, the shiny gloss cover was scratched, and on a couple, the black matte finish on the back cover was scratched off in places. Now, obviously, the latter two issues were the fault of bad handling somewhere along the way between the print shop's shipping department, to the book's placement on the shelf. But there is no excuse for the faded ink. And the decision to use the shiny, high gloss, and the black matte finishing on the covers, that are so easily damaged, are the product of faulty decisions. Neither is excusable, in my opinion, on a book with a price tag of $50 and some change after taxes.
I may not have cared much for 4e, but it seems to me the quality of the book covers and their bindings (not necessarily the art on the cover, mind you) was of much better quality.
