This comment made me start looking to see how often these things actually do drop. It's hard to get a truly accurate idea because most of the things that drop them have existed for long before this version of the DMF. Additionally, not everyone carries the books around, so the WoWHead statistics get skewed. Looking at just bosses that came with 4.3 is the closest to "accurate" one can get, but even that's not perfect since it was a couple of weeks after the patch before the first DMF happened, and again, not everyone carries the books in their inventory. From the various 4.3 bosses that drop them, though, the dungeon bosses have a 22% and 23% drop rate and the raid boss has a 45% drop rate. So I'd guess the dungeon ones are around a 25% drop rate and the raid ones are maybe 50%? I certainly pick up Soothsayer's runes every week and there actually aren't that many bosses that drop them.
