Classes: General
All healing critical strikes now heal for 2 times a normal heal (+100%), up from 1.5 times a normal heal (+50%).

Buffs
All class abilities which place a buff on friendly targets no longer generate any threat. This goes for raid-wide buffs like Mark of the Wild and Power Word: Fortitude, as well as triggered effects such as Blessed Resilience or Fingers of Frost, and single-target buffs like Dark Intent and Hysteria. The exception is buffs which directly cause healing or damage, such as Thorns or Renew. Abilities such as these still generate normal threat.

Pets
The Aggressive pet stance has been removed and replaced with the Assist stance. This stance will cause the player's pet to attack the player's target. The pet will not change targets unless the master attacks a new target for a few seconds.

Spell Interrupts
When interrupted while casting a single-school spell such as Mind Flay or Frostbolt, players will now be able to cast dual-school spells such as Mind Spike (Frost and Shadow schools) or Frostfire Bolt (Frost and Fire schools). However, being interrupted while casting a dual-school spell will still interrupt all respective schools as intended.

Lunar Shower has been redesigned. When casting Moonfire, the druid gains Lunar Shower. Lunar Shower increases the direct damage done by Moonfire by 15/30/45%, and reduces the mana cost by 10/20/30%. This effect stacks up to 3 times and lasts 3 seconds. While under the effects of Lunar Shower, Moonfire generates 8 Solar Energy, and Sunfire generates 8 Lunar Energy. The amount of Lunar/Solar Energy gained does not change based on the number of points spent in the talent, or stacks of Lunar Shower. Those druids who wish to delay transition in or out of an Eclipse state should now cast the one of their two basic attacks which will not move the Eclipse bar (either Starfire or Wrath).
Solar Beam has a new spell effect.
Wild Mushroom: Detonate can now also trigger Earth and Moon, in addition to Starfire and Wrath.

Restoration
Symbiosis (Mastery) has been removed and replaced with Harmony. Harmony increases direct healing by an additional 10%, and casting direct healing spells grants an additional 10% bonus to periodic healing for 10 seconds. Each point of mastery increases each bonus by an additional 1.25%. Healing Touch, Nourish, Swiftmend, and the initial heal from Regrowth are considered direct healing spells for the purposes of this Mastery. All other healing from druid spells is considered periodic.

Lightning Shield and Water Shield can no longer be dispelled.
Unleash Elements is now in the Nature school, and thus can no longer be used if a shaman's Nature school has been locked out.

Mana Tide now grants 200% of the caster's Spirit, down from 400%.

Set Bonuses
The 4-piece Elemental shaman PvP set bonus (Gladiator's Thunderfist set) has been redesigned. It now causes Lightning Shield to generate an extra charge, rather than consuming one, when it is triggered by receiving damage, up to a maximum of 3 (9 with the Rolling Thunder talent).

Professions
Skinning
Players can no longer skin corpses already being actively skinned or looted by other players.

PvP
Conquest Points
The minimum cap on Conquest Points earned per week is now 1500 at 1500 or less Battleground rating. The maximum cap remains 3000 at 3000 or more Battleground rating. The cap continues to scale non-linearly between those two points.
The game now separately tracks different Conquest Point caps for Battlegrounds and Arenas. The cap for Arena rating will always be 2/3 of the cap for Battleground rating at any given Arena rating. Players may earn a total number of Conquest Points per week equal to the higher of these two caps, but once players have reached the cap for either Arenas or Battlegrounds, they can no longer earn Conquest Points from that source. Conquest Points from Battleground holidays only count toward the total Conquest Point cap.

Quests & Creatures
There are no longer oddities in the critical strike and dodge chance of lower-level creatures.

User Interface
Raid Profiles are in the process of being implemented and are not fully functional. Raid Profiles will allow players to save the raid window user interface layout based on type of content (i.e. 10-player raids, 25-player raids, Battlegrounds, etc.).
