FULL HOTFIX NOTES HERE
________________________________________________

Hi all,

After carefully considering the constructive feedback we’ve received over the weekend, we’ve made some revisions to this week’s tuning. The class changes listed in this hotfix update, as well as those from the previous update will be applied during weekly maintenance in each region.

September 26 - Hotfixes
________________________________________________

Demon Hunter

Havoc
Bloodlet (Talent) now deals 150% of initial Throw Glaive damage.

Mage

Arcane
Quickening (Talent)’s maximum stacks are now 50, and it will not refresh its duration once at 50 stacks.

Priest

Shadow
Mind Sear damage increased by 80% and Insanity generation increased by 50%.
Mind Flay damage increased by 20%.
Mind Spike damage increased by 28%.
Void Ray maximum stacks reduced to 4.
Developers’ Notes: Given the damage increase to Mind Sear, Mind Flay, and Mind Spike, this still results in an overall increase to the value of the talent.
Voidform stacks no longer increase while Dispersion is active.Developers’ Notes: We would prefer that Surrender to Madness not be as dominant as it is, and that it can’t be extended for quite so long. However, addressing this further would require significant changes to the spec beyond what we want to do in a tuning pass at this time. We will look for an opportunity to take a more comprehensive look at this issue in a future patch.

Shaman

Queen Ascendant (Artifact trait) is no longer consumed when a queued healing spell is immediately triggered.

Warlock

Fixed a bug that prevented Rain of Fire from always doing all 8 ticks of damage on PvE and PvP targets.

Warrior

Arms
Tactician proc rate increased by 15%.
Hamstring no longer procs Tactician.
Exploit the Weakness (Artifact Trait) bonus reduced to 4% per point.
