End-game (level 60):

Elianna’s Level 60 Disciples of Hand and Land Guide: Google doc
Have you dinged 60 on a DoH/DoL job, but feel overwhelmed by the vast range of end-game systems? This guide does a great job of explaining collectibles, scrips, aetherial reduction and gear (note that it doesn't cover patch 3.3+ gear other than a note at the end of the guide). The rotations in the guide may still work, but there are better ones in the Rotations section below.

Folklore Nodes, Ephemeral Nodes, Unhidden Nodes and Rotations: Google doc
Tables with locations, times, etc for folklore, ephemeral and unhidden nodes. Has a rotations section at the bottom for gathering collectibles for scrips and counterfoils.

Rotations:
