Thanks for your questions!
- The older edition also had the text, "Ranged weapons are always fast for the purposes of defense, regardless of damage die." The newer release doesn't have that text, but just has it in the tags. I figured it made more sense for ranged weapons to always be Fast, though you could argue that the drawing of a giant bow would take time (and if it fires a single spear-sized arrow, you might still want to Dodge.
- You are completely correct! I changed the Difficulty, but forgot to update the example. I'll do that in a future version!
- BDP builds upon Cairn. I don't have any rules that add or modify Armor in any significant way in comparison to Cairn, so the base rules cover that quite well. In short, Light Armor gives 1 Armor, Medium Armor gives 2 Armor, and heavy, expensive plate gives 3, with a Shield giving +1. I'd have cheap Light Armor be Bulky, expensive Light Armor just be 1 slot, and perhaps have Medium Armor always be bulky.
