The one thing people have trouble in the game is having enough gold for their character.
If you are in need of gold, this gold farming guide will answer all your problems.
Buying gold is one of the dumbest things you can do! You are wasting your money on something that isn't even real.
Also, why would you buy gold when you can be making tons by yourself? Obviously, the best method is by using Auctioneer, but it's pretty complex to learn, so I will discuss some of the things not related to Auction house here.
The best gold farming guide will not work anymore because of WOTLK.
There are new things that happened because of the release of WOTLK.
The first method you can use is farming cloth! Wool cloth, mageweave cloth, and runecloth have SOARED SKY HIGH in prices after the release of WOTLK.
They are selling anywhere from 6-15g on servers average.
Wool cloth can be farmed in Shadowfang Keep, Mageweave at Zul'farrak, and runecloth in just high level mobs with humanoids.
Another thing that happened is the rise in prices of bars and ores.
Miners can be rich now! Silver ores sell for about 5 gold each which is stunning.
Copper bar and ore will sell for about minimum price of 6g a stack now, and other ores and bars have rose in price dramatically.
These are the best gold farming guide in the new expansion WOTLK, but there are guides written by professionals out there from which you can benefit greatly from!
