joana horde guide was written by Joana or Mancow as others know him. He has set records on multiple servers for being the fastest to reach level 60. After checking out his horde leveling guide, I know why. Not only does the guide go indepth with how to power level a horde character, Joana also provides video support of his journey. I was able to watch him go from 0-60 as if I was looking over his shoulder while he was playing.
The video quality is very good. Having the videos alone would justify picking up Joanas Horde Leveling Guide, but I kept finding more and more good stuff inside. Joana broke down the quest for each horde race. Someone starting as an Orc, like myself, would get just as much use out of the guide as someone that wanted to start as an Undead or Tauren. Joanas guide also has a section for the new Blood Elf race as well.
The answer to that question is utilisation of TIME !!!! What the joana horde guide does achieve is to explain the path used by a WOW power leveler. What it doesn't address however is the actual way a power leveler in WOW spends his time.
The guys who Level they're characters to level 70 at blistering speeds obviously have a huge knowledge already embedded in they're brain of where to go and who to speak to, they have played different characters and classes numerous times and when they enter an area, for instance Strangle Thorn Vale they know exactly what route they need to take. They do not stop every batch of quests or single quest to Alt-tab out, to check they're copy of joana horde guide
