Similarly to Alliance’s Paladin, Shaman is a unique class option for Horde. Shaman boasts amazing group utility with its strong buffs through totems. Windfury totem is a must in any raid while Bloodlust in Classic is unique to the Shaman class. Restoration Shamans were considered the best group healers while other specs were also amazing in PvP environment capable of dishing out insane burst damage. Additionally, Shamans were able to wear mail armor, so any piece with spell power on mail set piece was almost certainly yours.
The item they're dropping is the Fused Wiring used in a variety of engineering recipes such as: Field repair bot, Gnomish cloacking device, Goblin jumper cables, mechanical dragonkin and so on. The drop chance is estimated to be around 6% and due to the fact that there only 3 spawn points and this is the only somehow efficent place to get it... the price of it on the auction house is anywhere between 5 and 10 golds, sometimes even more.. you know.. supply and demand.....
Always sell all items on Auction House. If you are not sure about its value, then check the market. There are some risks that item won’t be sold and you will lose money just putting it on Auction House. Good idea to make bank low level characters and keep everything there until the weekend. All sales increasing on Friday, Saturday and Sunday. Besides, you can advertise in a trade channel to inform people that an item you are selling has been put on Auction House.
