Faceless Entertainment is currently working on a new PDF product for Pathfinder. The book will contain a number of NPCs with stat blocks for each one at a variety of levels. At each level the NPC's back story will progress forwards in order to keep in tune with their new abilities. My question is, which one of the following options would the Pathfinder community find most useful.
1) NPC focused, with each NPC having their own section with their stat blocks for each level arranged in order.
2) CR focused, with the stat blocks for all NPCs placed together in sections divided by level.
If you think one of these would be particularly useful, or have another suggestion, please let your voice be heard.
