Kill quests aplenty.
Our Horde Leveling Guide has been updated to walk you through level 32.
To complete your thirty-second level we are going to return to the
Thousand Needles zone. This time though we will move to the salt flat
type area at the east end of the zone called the Shimmering Flats. For
what initially appears as a barren section of land, there is a ton going
on there. It should keep you busy for quite a while.
Without further delay, I present our leveling guide from level 20 to 60. This guide is meant to show you the fastest way to level from 20 to level 60. This is from our experience and research and has proved to be very fast, however there is always room for improvement. So if you see spots for tweaks, please send them in!
Go get leveling! More info at Ten Ton Hammer's WoW site.
