The print version of the official strategy guide list all dynamic events and hearts with description of event, etc… with the exception of three zones. Timberline Falls, Sparkfly Fen and Mount Malestrom (all 55-70 level zones) For these zones, they just publish a picture of the map revealing heart and waypoint locations but no description of dynamic events.
It seems perhaps these zones were not finished when the book went to press. Perhaps it’s not coincidence these zones feel like an unfinished mess that you must grind your way through?
IMO these zones feel very unfinished.
