Clearly is was a mistake to make the best source for farming phil tomes in two story dungeons. This has been a big point of contention. Now that WP and AK give 100 phil tomes, there is really no need for speed runners to do CM or Praetorium, and those playing the story can do so without harassment. This seems to have been the main point of this change. Besides, AK is faster simply because it doesn't have so many cut scenes to skip.
