With World Of Warcraft - Cataclysm released, people saw some significant changes in professions and material gathering. One of the professions that saw a msjor pinch is Tailoring. Unlike previous versions of WoW, cloth drop is not as frequesnt as it used to be. In earlier versions, I had so much cloth in the bank that I could not figure ot what to do with it. Now you have to pray when you kill a humanoid that it has one piece of EmberSilk on it. And when it drops then you are thinking about if you want use it to make bandage or not. So you already have two professions competing for a rwsource that has become rare.
Anyways here are some of the tips that I think will help you in farming Embersilk in Cataclysm
I hope these few tips help you in farming Embersilk cloth little faster.
