One of the first leveling guides in World of Warcraft is Joanas Guide.  Joana or Mancow is the writer of this leveling guide.  He brags about his success in the old Blizzard contest for speed-leveling.  He assures his readers that all will achieve similar speed for leveling.

Questing is quite simply the fastest way to level.  The best leveling guide is something that will tell you what exactly is the order to do quests.  Players who know zones will level even faster than with a smart newbie if they chain together the nearby quests and will not waste too much time.  Experts do this even better.

The Horde Leveling guide provided by Joana will put you bit ahead of the “knows the zone” level but not quite to the expert level.  There are only few sections that are difficult for some classes as Joana is a great player and great players are good levelers when solo.  Some classes will find that guides is of course downright unpleasant if they are not geared well.  Those with no experience at all with such guides will surely wonder how the knowing of the quest order will really help especially if they never done these before.  This guide uses map coordinates which gives simple connection to travel in.
