World of Warcraft Horde Grinding Guide
The First,You want to do quests until you hit level 30 before you start grinding.
Once you hit level 30 then go to Shimmering Flats and do all the kill quests and grind on the basilisks around the small lake to the south of the race way until you hit level 33-34. From there if you have higher level help you can go straight to Scarlet Monastery and have them help you grind out that instance several times until you hit level 40. I find this way to be the quickest and best, but only with higher level help.
If higher level help isn't available you still want to do the Scarlet Monastery quests but don't waste your time trying to find group after group after group to do it over and over again as this takes way too much time.
