It's hard for me to believe that Cataclysm has only been out for slightly over one year, especially given how we're already on the last raid of the expansion. It's been a turbulent year for the shaman class, and elemental as a spec is no exception. Between legendaries, highly fluctuating DPS, and more tweaks to AoE then I care to count, elemental has had more than its fair share of ups and downs this year.
Tier 11: The lows
Elemental was not a strong DPS class in the first tier of Cataclysm raiding. Fights like heroic Halfus, Maloriak, and Sinestra brought our lack of competitive AoE damage into the limelight, while Cho'gall, Conclave of Wind, and Ascendant Council all highlighted how elemental's mobile DPS was terribly low. With Unleash Elements and shocks being our only mobile cast -- not to mention low levels of haste that left us with terribly slow Lightning Bolt casts -- and we really struggled to pump out respectable numbers on any fight that wasn't Patchwerk-esque.
