There are many methods for making gold in World of Warcraft, but I think farming wow gold in instances is the best one, because other methods have certain flaws. Take grinding and using Auction House for example, grinding is boring and you have to know exactly what spot to go to; if you chose to use the Auction House Domination technique, you need to know much about the economy on your server. While there are no flaws with Instance gold farming, only benefits.
