My best guess is he's writing these things with Adventure League in mind. The kind of groups where DM's rotate, new players keep showing up, and the sessions are so short that the focus really is more on getting your 6-8 encounters in for the night than attempting to setup plausible RP or story sets. I wish he'd start writing higher quality stuff again, but I suspect this isn't happening because he suddenly became a crappy designer; he's just pandering to a niche in the community.
Nah, like I said in my review, I don't think he had the time or resources to do anything more. It really looks like this book wasn't really meant to be a campaign but rather a sourcebook for the north and then later someone said, "We need a campaign book, stat!" It has all the hallmarks of adventure being tacked on as an afterthought without a team to actually review and playtest it through a proper product cycle.
What annoys me is that I have to do so much work for it to make sense. Like this section I'm going through now, I'm rewriting half of it. That was work I specifically didn't want to do, which was the entire reason why I wanted to run a campaign from a book in the first place.I've read whole sections 8-9 times, trying to make sense of it, and yes, it's bewildering. I'm just hoping that my players don't try to delve too deep. With any luck, they're charitably assuming that, behind the scenes, it all makes sense.
