When an Enhancement spec Shaman reaches the seventh tier, they gain Storm-strike, which gives them a chance to attack with Eve isk both of their weapons and to greatly increase the damage that is done by their next two Nature spells.
While the Enhancement spec offers great perks to those in the PvP area, it might not be the best way to go for those in the PvE areas.
The Restoration talent tree enhances the Shamans ability to heal by reducing the casting time and the mana that is used to cast healing spells. It also helps to increase the abilities of totems that are cast, which is a great perk for those who prefer the healing role of the Shaman.
For Shamans who take on this spec, they will almost always be picked up by parties in the end-game raids and instances, as they provide a healer and great buffs with their totems.
The Enhancement talent tree enhances the Shamans abilities to provide special timed enchants on their weapons and to expand on their melee abilities.
This talent spec is appealing to lower level Shamans since it offers a mana increase, reduced cast time, and gives them the ability to use two-handed weapons.
