Didn't buy it and glad I didn't - I was disappointed with how with the exception of the arcanist it seemed that a lot of play test advice was ignored. Bad technical editing and poor understanding of their own systems balance just seems (by the posts here and elsewhere) to have created a poor all around product.
Frankly I lost faith in Paizo's technical editing when they screwed up class features RIGHT there in their own rule books when they did the Sword Saint samurai archetype and with the many screw ups with Ultimate Combat. Not sure if they even bothered to errata the Sword saint yet either.
Happy to play the game but I don't buy the new stuff anymore (not since UC I think) - the quality has gone down hill whenever they have a major publishing deadline. I am happy to hear that MAYBE Occult Adventures may be of a better quality than this book.
