Shamans can also use their specific talent trees to further their customization
General Shaman Information:
Shamans are considered to be one of the most diverse classes in the World of Warcraft. Known for their abilities to heal, melee DPS, and range DPS, these classes are a great asset to any tera gold guild or group.
Shamans can enhance any party, since they don't have to be completely focused on one specific role, such as healing. Shamans can also use their specific talent trees to further their customization of their character towards healing, melee, or spell-casting.
Their primary support to their group, and themselves, are their totems. These totems provide protection, healing, mana, and even do damage to mobs that come in range of them.
Shamans also have the unique ability to resurrect other players and themselves, which can come in extremely handy when in a dungeon or on a group quest.
Alliance players couldn't play the Shaman and the Horde players couldn't play the Paladin, and the game was set up this way to balance out the field with these types of classes.
But, with the release of the Burning Crusade expansion pack, the Horde now has a chance to play the Paladin and the Alliance now can play the Shaman with the Draenei.
