For me there was an interesting comparison between Dark Harvest, which had very grounded/believable settings and was easy to pick up, and the latest Gotrek book, which was a little fantastical for me. Grubby villages and straightforward roles for supporting characters vs a high fantasy setting and characters that I struggled to visualise. It’s a bit of a trap AoS can fall into from time to time and can make it hard for BL novels in the setting to shine.
For me the limited edition release schedule doesn’t work, I’m just not going to drop that much on a book and some of the excitement has then worn off by the time the hardback comes out.
I think the AoS side suffers from lack of big name characters for novel series and porting Gotrek over was ok but slightly flawed. I’m not sure what to suggest there as for me the kore interesting perspectives e.g from a normal human/free guild are a bit hobbled by the faction having been more or less abandoned in the game. I like to be inspired to pick up some figures after my reading and get painting!
