Surprised no one has posted these yet. Wowhead has them at Item sets - World of Warcraft. Here are the set bonuses:

Druid (resto and feral) - increases your movement speed by 15% while in Cat, Bear, or Travel form
Druid (moonkin) - reduces the cast time of your Entangling Roots by 0.15 seconds
Hunter - reduces the cooldown of your Multi-Shot ability by 1 second
Mage - reduces the cast time of your Polymorph by 0.15 seconds
Paladin (all sets) - reduces the cooldown of your HoJ by 10 seconds
Priest (all sets) - reduces the duration of the Weakened Soul effect of your Power Word: Shield by 2 seconds
Rogue - increases your maximum energy by 10
Shaman (elemental) - gives you a 70% chance to avoid interruption caused by damage while casting Lightning Bolt
Shaman (enhancement) - reduces the cooldown of your Stormstrike by 1 second
Shaman (resto) - reduces the cooldown of your Grounding Totem ability by 1.5 seconds
Warrior (all sets) - reduces the cooldown of your Intercept by 5 seconds
Warlock (all sets) - reduces the casting time of your Fear by 0.2 seconds

The bonus that really catches my interest is the Elemental Shaman one. It's going to completely remove one of the biggest liabilities of the class in 5s (you can't cast while you are being attacked). Pretty nuts. Perhaps they will change the shadow priest bonus from the current Weakened Soul garbage to something similar for Mind Flay.

They also mentioned they might change the buff on gloves - hopefully so priests get something better than the shitty glove bonus.

Strange the blizzard nerfed their burst DPS potential with the LO change, but then added this to the gear. I am not sure what they are trying to do accomplish, balance-wise, with elemental shaman in PVP at this point.

Also strange that the moonkin bonus is the same as the mage one, except that the form of CC it is applied to is significantly less useful; one would think the cast time reduction should be increased in that case. (See warlock bonus)

Well, these boni are not just S3, but also S1 and S2, because all items even from different season are now belonging to the same set.

The new elemental one is really great. From one of the weakest (2% crit to shocks, lol) to a very strong one. Can't wait to test this one.

It's easy to see that they wanted to nerf the shaman's burst, but then compensate by buffing their damage output outside of that.

Shadow priests should probably get a different bonus than holy priests. The moonkin one seems pretty useless to me, you'd think they'd give that bonus to cyclone instead, a CC that actually is useful.

I am rather disappointed at enhance bonus (as i heard the elemental bonus before), but maybe at least gloves bonus will be better.

What does that have to do with 4p set bonuses? They aren't mutually exclusive.

Then it becomes the same as saying mages should have an additional poly shortened cast time on their gloves. Stacking quicker CC casts just leads to more people wanting their CCs quickened. Asking for that for druids just leads to other classes also wanting it. I midly agree the roots buff is lame, but I think an additional cyclone buff would be a mistake.

Color me surprised.

Surprising how much difference there still is between classes. The hunter bonus is.. again, not really amazing compared to the warrior or rogue one for example.

Depends what side of the fence you're on. For example, the rogue bonus seems to be rather useless since the days of 120 energy double backstabbing seriously denting an opponents life are long gone.

Indeed. I've always been really underwhelmed by the bonuses on our pvp gear. I *rarely* get to cast FoL in arenas (moreso in 2v2, but even that is very situational), yet our gloves give it 2% crit and our libram only procs on FoL, and not Holy Light. I'm really hoping they revise the healing libram for 2.3, but I'm thinking it's rather unlikely.

Apparently its too much to expect Blizzard to know how to play a perspective class in an arena setting beyond the 1600 bracket.

Good news, however, most of the dispel effects (cleanse, remove curse, etc) have been upped to 40 yards - same range as max range heal.

Yeah, that alone is enough to make me excited for 2.3.

Hm. It would not surprise me for Blizzard to revise these set bonuses again. The Hunter bonus is underwhelming, but the elemental shaman bonus appears to fit the class' needs for PvP extremely well. Hunters and Shamans both suffer from extreme interruption on Steady Shot and Lightning Bolt in PvP, so perhaps the Hunter bonus will be revised to a 70% resistance to shot interruption when casting steady shot, or a similar bonus.

Makes sense, right? Fear is by far the worst CC and therefore needs a bigger casting time reduction [/sarcasm]. I don't understand why Blizzard gave Warlocks such a crutch when casting Fear, who cares about fake-casting when your fears are 50% less likely to be interrupted and are only a base 1.3 seconds to cast? I don't really see any logic in the numbers Blizzard put out there. Why should Sheep and Entangling Roots be penalized .05 seconds when Fear is far superior to both (especially Sheep, with the removal of Detect Magic from the game)?

As far as the Elemental Shaman bonus goes, I think it's going to be a big deterrence to focusing an Ele Shaman, which should be a relief for them. Unfortunately, that means Mages are probably going to see more focus fire, especially with the added 15 seconds to Hypothermia (as if it wasn't hard enough to kill a mage in 30 seconds before... and so the gap between Mages and Warlocks widens further). Honestly though, I would've preferred to keep Empowered talents the way they were and keep the 30 second Hypothermia.

I think a 0.05 second discrepancy isn't very relevant when you step back and look at how powerful the warrior and elemental shaman bonuses are.

Edit: 4 peice resto aws changed to 1.5 seconds.

I would rather have the mage bonus give mages Detect Magic back. The elemental bonus however is very strong. Edit: Warriors always had 15 second PvP intercept. What's so strange about it?

warrior: 5sec/20sec = 25%

warlock: .2/1.5 = 13%

mage: .15/1.5 = 10%

That is what is so strange about it.

Hunter: 1/10 = 10%

....

Well, i suppose it could be +30 resilience or something even worse... but honestly, Multishoting in the arena is VERY situational.
