I finished the DLC. It's a bit on the short side considering the price (even with the personal quests, I don't think it can take more than 10 hours for a completionist) and buggy, but I don't really think the content itself is a problem.
It's a pretty well done new area with some cool additional lore and a bunch of different ways to solve situations (there's also a bunch of reactivity to Conquest and faction choices, which is cool). There isn't even that much combat (which isn't great, it's mostly just Bane coupled with humans and Beastmen), most of the time I spent actually doing side quests, exploring and doing dialogue challenges.
All in all, I recommend waiting for a couple patches and maybe a sale, but I enjoyed my time with it.
