Allow you to talk with a microphone to people of your group
As of patch 2.2 Blizzard introduced in game voice chat. This allows you to talk with aion kinah a microphone to people of your group, raid, or custom chat channels.
The voice chat that Blizzard introduced is not as high quality as Ventrilo, but it is free with the game. Ventrilo has a cost that someone commonly donates to the guild to pay for it. Blizzard's voice chat will phase third party voice chats out over time.
With all of that said, let’s move on to what shamans actually do. Shamans are a hybrid class of warrior, mage, and priest.
How you choose your talents will determine what kind of shaman you are. You will use your other totems based on the situation. You have five main spells that you are going to be using: Lightning Bolt, Chain Lightning, Earth Shock, Flame Shock, and Frost Shock.
The three most common names for shamans are: Restoration shamans, Elemental Shamans, and Enhancement shamans.
In most raids, Restoration shamans are the most sought after and Enhancement shamans tend to be the least sought after. Your role during the raid will depend on what niche you where invited for - Healing, DPS, or Tanking. It will take doing raids to learn exactly when you should start that heal, or when you should be able to cast another lightning bolt.
