When I first bought it, it was far less edited and far mroe spotty. Things were iffy, and confusing.
After a few months wait, and a good bit of playing while errata was released, ; I've deicided that this has 5 stars. It's meaty, but approachable, it's gotten updates that had things taken from the playerbase by the writers /e diters / whatever, and it's been cleared up by and large. There are still some editing and layout issues in the book, but I don't hesitate at all to give the game / book 5 stars.
If you're interested in WH40K, especially after some of the lore going on in 8th edition ; Wrath and Glory is for you. I'm strongly looking forward to USNA's furthering of this gameline - hopefully allowing for playing Tau (Especially of the Farsight Enclaves) or of Adeptus Custodes or Grey Knight Space Marines.
I'd also just laugh heartily if for some absurd reason straight up Daemons were made playable in later things, with th odd consideration for Chaos forces in even this book.
