I am really looking forward to
this supplemental codex release. It's been an expensive two months for me, as I collect Grey Knights, Necrons, Blood Angels, and Dark Eldar. I've always loved Harlies, and I'm glad that they are getting a dedicated demidex. The aesthetic of the solitaire is not something I like, but I'm not complaining. I'll figure out how to convert it.
I really hope Sisters are on the roadmap.
