Joana's Leveling Guide was written by the player, who has the fastest 1-60 leveling speed in the world. It took him only 4 Days and 20 Hours. In his guide he describes the same methods, strategies and techniques which has helped him to achieve this leveling speed. However, while other guides contain only text information, Joana's Leveling Guide also contains video guides and interactive map coordinates (mapmod).
As for me, the videos are a very useful feature as it shows you every move Joana did to get to level 70. Using mapmod you don't have to press ALT+TAB every time you need to find your next coordinates so you can concentrate on your leveling process.
