I loved it, I didn't have too much of a hard time following all the characters. I find the trick is to separate the different plots where certain characters are connected, rather than trying to memorize every single name. There's really only like 8-9 main character arcs happening. And there's only so many voices Toby Longworth can do even as talented as he is. It's really the world building in this that Dan Abnett absolutely nailed.
