Whenever people mention normal leveling up at high levels, they mention these places: Lhusu mines extension, Henne mines extension, Giruvegan great crystal, Pharos subterra. They also sometimes mention Necrohol of Nabudis and Nabreus Deadlands.

These places will take a long time to get up to level 99. I would like to do those auto-levelling tricks instead, I'm researchign them today.
