PvP Power
-- On live, PvP Power grants 0% healing to Balance, Feral, Windwalker, Retribution, Shadow, Enhancement and Elemental. In the next 5.2 build, this number will be 25% (or half of what a healing spec gets). We agree that PvP healing feels too weak for these hybrid classes. We also don't think Shadow really needs this buff, so we will likely offset it in other ways.
-- We are working on a blog (hopefully next week) to explain some of the other changes to PvP gear in 5.2. We hear your concerns and are trying to address them.

Paladin
- The Protection 2pc is additive. It's duration is 5sec per Holy Power. We realize there are concerns about this enabling block capping, and are keeping an eye on this, and will adjust if necessary to make sure it doesn’t happen, even later in the expansion.
- The Protection 4pc does incentivize Unbreakable Spirit. We’re considering possible revisions but want to try it like this for now. It's currently "You gain 1 Holy Power for each 20% of your health taken as damage while Divine Protection is active."
- The Retribution 2pc is a debuff on the target, and does not stack or roll. With Glyph of Mass Exorcism, the debuff will be applied to all targets hit by the Exorcism. It affects all of your Holy damage. Yes, that includes Seal of Truth, Censure ticks, and Hand of Light. Censure ticks are affected per tick -- whether it was up when Censure was applied doesn't matter. It functions similar to the increased magic damage taken raid debuff, except is Holy-only and self-only. Clipping some debuffs when you get back to back Art of War procs is expected, and balanced around.
- The Retribution 4pc does grant a self-buff that is consumed by the next TV, and does not stack. Wasting some procs is expected, and balanced around. Yes it is a single-target benefit that won't increase DPS on AE fights. We don't want to be in such a limited design space (we're talking about the 15th tier here after all) that every set bonus must be super generic and work in every situation. If anything, we'd rather the Ret bonus be even higher for single-target and paladins will just be stronger at single-target and weaker at AE once they have the set bonus than they are in other tiers. Set bonuses are one of the few chances we have to change what your character does (within reason) aside from all of your numbers just getting bigger.
- We changed the Repentance cast time to make it consistent with other cast time crowd control. A 1.5 sec cast time (reduced by haste) gives little opportunity for interruption.

Rogue
- During Shuriken Toss, your auto attacks are replaced with throwing Shurikens, which do 80% weapon damage, but are on the 'yellow combat table', meaning they don't glance, and don't suffer the dual wield miss penalty. The 80% number was chosen because that approximately offsets those other benefits.
- In our above description of Blade Flurry, 'normal' means the same as it previously did; that is to say, the damage that the ability would have done had it hit the secondary target.
- The 2pc does encourage using Rupture as Combat. 
- Burst of Speed saying "movement-reducing" means that it no longer breaks roots, but does break snares.
- We are experimenting with allowing Smoke Bomb to reduce the damage done to allies by 20%. We agree that rogues are lacking in the group utility department and we'd like to see less use of Smoke Bomb strictly as an offensive ability in PvP.
- We are going to reduce the PvP set bonus from +50 energy to +30 energy.

Monk
- Storm, Earth, and Fire does not affect Xuen's damage. The spirits benefit from your Tiger Eye Brew. We agree that a spell with "storm, earth and fire" in the name sounds like a shaman spell, but Warcraft 3 established it as a Pandaren monk ability.
- The Mistweaver 2pc is multiplicative. The first target gets normal healing, the second gets 115% of normal, and the third gets 132.25% of normal.

Hunter
- The 2pc and 4pc both can crit.
- Direhorn Stampedes are everything you dream them to be.

Druid
- Please note that Restoration Mushrooms are currently incorrectly absorbing 33% of overheal each, instead of 25%.

Shaman
- The Elemental 4pc does trigger from Overloads.
- We're still iterating on the cooldown/potency/duration of Elemental Mastery. In the next PTR build, it will likely be a 90 sec cooldown. 
- We are experimenting with removing the attenuation of Chain Lightning. This means Chain Lightning won't do less damage on subsequent targets.

Priest
- The Shadow 2pc does impact Shadow Word: Insanity, which we're working to resolve. It extends existing effects, preserving their same damage (not recalculating).
- We are considering making the glyphs of Desperation and Inner Focus passive for Discipline.
- We are considering giving Focused Will to Holy as well as Discipline.
- We did not buff PvP Power for healer damage as we did for DPS healing. However, we believe that Discipline specifically might need more damage. One potential solution is to nerf Atonement healing but raise damage so there is no net healing change.

Warlock
- With the 2pc, an Incinerate crit has an 8% chance to generate 4/10 of an ember. Yes, this will apply to Fire and Brimstone Incinerates.
- We are strongly considering allowing Dark Intent to provide Stamina so that warlocks don't feel like they must use their imp.

Warrior
- A Prot Warrior using 2 pieces of the DPS set will get 1.0 RPPM of the enrage.
- We agree with concerns that the new Arms rotation doesn't involve much rage management. We are considering a small rage cost for Overpower. Arms will likely need some additional retuning of damage because of the changes to Overpower, Taste for Blood and Slam -- we haven't completed tuning yet.
- We made a change to warriors to double the effect of haste for them. This is similar to the shaman Flurry benefit, but is passive and not tied to an ability. We want to make haste a better stat for warriors without it eclipsing stats like crit -- we aren't trying to force every warrior to reforge.

Promises
We're not making any (except maybe that Direhorn Stampede bit). We're providing you some notes of changes we are currently trying in order to provide you context for some of the other class changes. Many of these may not make it to the live game -- that is the nature of a PTR. As always, we appreciate feedback on any of this.
