ok, happened to be looking around for more info on drops for APW armor molds so i could post a link in the wishlist topic, and found this little gem. For anyone who is interested in raiding, this would probably be very helpful. I mean both New and Veteran alike. I remember one of my old guilds linking to this, and thought it would help. There might be some information that will help you.
