Here is a WOW leveling tip for Humans in Wotlk World of warcraft. Enjoy!
In World of Warcraft, Human character is starting in the area called Northsire Valley. Start doing the quests here, when you done, go to Goldshire and do the remaining quests. There are some tricky quests, so be careful with them. Then go to Eastvale Logging Camp where you can do another bunch of quests. After you complete all the quests in the zone you will be at level 10, so it is time to go to Westfall.
The second task when you level a human character is to choose the best add-ons for WOW power leveling. In my opinion, one of the most helpful add-ons is the Cartographer, since it unveils the whole map and shows your exact coordinates. Another very good add-on is the Gatherer, which helps you find the materials for your chosen profession.
Choosing the best talent is one of the most important task. A good talent build can turn your character into an unstoppable killing machine, while a weak one will cause you constant frustration. In general, go for damage instead of healing or defense. Damage is what really matters. More you kill more XP you get, so simple.
Hope this free and simple WOW powerleveling guide will help you for your human character, happy leveling.
