WotLK Enhancement Specs
11/60/0 - Raiding
This build would be a pure-raiding build as it sacrifices the quick getaway moves of Improved Ghost Wolf, doesn't have any of the defensive talents of Anticipation or Toughness, and skips Spectral Transformation. It does go deeper into the Elemental tree to bring more usefulness out of Lava Burst. Finally, it also taps into the passive dps of Static Shock+Improved Shields.
0/65/5 - PvP Defensive / PvE Solo
In this build I'm focusing on defensive abilities over offensive. While Anticipation can be a liability against Warriors, I put points into it as an added safety net against those filthy rogues. As for Maelstrom Weapon being worthwhile in PvP situations I'm undecided on it. It would require 5 critical strikes on 1 target, and each must occur within15 seconds of the last crit to keep the stacks going. It may have usefulness in certain situations where that extra damage from an insta-cast Lava Burst could put you over the top, but that remains to be seen. I will test both with and without Maelstrom when the time comes. This build would also serve well for soloing in PvE content because of the defensive talents.
8/63/0 - PvP Elemental Devastation
A more offensive build than the one listed above, it does not include Anticipation but still puts points into Earth's Grasp and Guardian Totems. This one dips down into Maelstrom Weapon and then put remaining points in Elemental Devastation. I can see this being a very effective build for PvP that will capitalize on the shaman's burst damage and make casting viable while ensnared.
