With the Circle of the Crone being my favorite Covenant, I was happy to see the new Theme based system for blood magic that gives much more flexibility with rituals. Only thing I found disappointing is the new system no longer allows the use of Spirit Cruac rituals that appeared in the Circle of Crone book. For STs who don't usually play or run Mage: Awakening, but want human magic user NPCs in their Requiem game or other genre, the new system in Blood Sorcery can work well as an alternative magic system for Thaumaturges and Mages.
