Evoker
    Augmentation
    Developers’ notes: Augmentation is overperforming in dungeons and is doing less direct damage than intended relative to the power of their buffing effects. These adjustments will increase their personal damage in all situations and moderately reduce the effectiveness of their buffs in dungeon content.
        Close as Clutchmates now causes Ebon Might and Breath of Eons to be 20% more effective when not in a raid (was 40%).
        Fixed a bug where Close as Clutchmates would not increase the Evoker's damage done via Ebon Might for periodic effects such as Fire Breath.

Mage
    Master Shepherd increases Versatility by 12% (was 6%).
    Arcane
    Developers’ notes: The high-end burst damage of Arcane Mage was reduced with the release of Fractures in Time, so we’re increasing the damage of Arcanosphere, as we’d like it to be a more threatening piece of Arcane's toolkit. We’re also increasing the baseline damage of a few rotational spells, as Arcane's overall damage has been lower than we would like, and Nether Tempest has not felt like a competitive spell in PvP.
        Arcanosphere damage increased by 25%.
        Arcane Missiles damage increased by 12% in PvP Combat (was 5%).
        Arcane Orb damage increased by 30% in PvP Combat.
        Nether Tempest damage increased by 150% in PvP Combat.
    Fire

        Fire Blast damage reduced by 3% in PvP Combat (was 8%).

        Living Bomb damage increased by 300% in PvP Combat.
    Frost
    Developers’ notes: We would like Ray of Frost to remain a threatening cast, but still feel it’s slightly more lethal than we’d like. Frostbolt's damage has fallen behind other options, so we’re increasing its damage to reward casting. Snowdrift's activation has felt a little too difficult for the amount of risk involved, so we’re reducing the time to trigger the stun effect.
        Cryopathy is now 50% effective in PvP Combat (was 60%).
        Frostbolt damage increased by 150% in PvP Combat (was 100%).

        From Darkness Comes Light now stacks up to 25 times in PvP Combat (was 50).

Monk
    Yu'lon's Grace effectiveness reduced by 50% in PvP combat.
    Windwalker
    Developers’ notes: Windwalker Monk's damage profile is more bursty than we would like, so we are moving more of its damage into base rotational spells.
        Rising Star critical strike damage bonus is now 50% effective in PvP Combat.
        Serenity now increases damage and healing by 10% in PvP Combat (was 15%).
        Whirling Dragon Punch damage is now increased by 120% in PvP Combat (was 80%).

Shaman
    Elemental
    Developers’ notes: We feel the backlash damage from Flame Shock has not been sufficiently high as to make the decision to dispel it compelling.
        Control of Lava damage increased by 40%.
        When gaining the Ascendance effect, Lava Burst will no longer automatically be cast on a player target affected by crowd control that breaks from damage.
    Enhancement
    Developers’ notes: We feel the backlash damage from Flame Shock has not been sufficiently high as to make the decision to dispel it compelling.
        Control of Lava damage increased by 40%.
    Restoration
        Now regenerates 700 mana per second at max level in PvP Combat (was 800).

Warlock
    Abyss Walker is now 100% more effective in PvP combat.
    Impish Instincts now reduces the cooldown of Demonic Circle by 3 seconds when triggered (was 2 seconds).

Warrior
    Slam damage is now increased by 85% in PvP Combat (was 48%).
    Arms
    Developers’ notes: We’re increasing the damage of Bladestorm baseline and removing some power from the Unhinged talent, as its damage could be unpredictable for both the Warrior and their enemies. We’re also increasing the damage of Overpower to increase Arm Warrior's consistent pressure.
        Overpower damage is now increased by 30% in PvP Combat (was 20%).
        Bladestorm damage increased by 40% in PvP Combat.

        Onslaught damage increased by 15% in PvP Combat.
