The extent of the hotfix nerfbat has just been communicated by Ghostcrawler.
As I stated yesterday, we are happy with Ret's PvE damage and sustatined damage in PvP, but were concerned that the burst damage in PvP could be too high. We discussed this for literally hours yesterday, which was certainly not the first time we have discussed the issue. Thus I hope these changes are not perceived as a knee-jerk reaction, but I am sure that will depend a great deal on which class you play. :)
Divine Storm -- the damage was changed from Holy to Physical. As you know, Holy damage is almost never mitigated and this talent could pack a lot into a very short time. This is a nerf to the ability's damage. This change is now active on Live.
Repentence -- this ability now lasts for only 6 seconds in PvP (down from 10). Obviously this is also a nerf. This change is also active on Live.
Art of War -- now affects all damage done by Judgements, Crusader Strike and Divine Storm (instead of critical strike damage). Net dps should be about the same but less bursty. This change will be made before Nov 13.
Righteous Vengeance -- now applies a dot affect similar to Deep Wounds (instead of critical strike damage). This ends up being a significant buff to the ability to make up for the damage lost to Divine Storm, but is also less bursty. This change will be made before Nov 13. This dot will also not break Repentence.
Glyph of Crusader Strike -- now reduces mana cost (instead of increased damage on stunned targets.) We thought paladins could stack too much damage vs. stunned targets. This change will be made before Nov 13.
We also fixed a bug with Seal and Judgement of Light that could sometimes result in too much healing.
In our tests, Retribution dps remains the same over longer periods of time, but they can't do quite so much damage in the initial few seconds of a PvP encounter.
I know Ret pallies feel a little picked on since we've made this mistake before of having them come out the gate too strong and then had to correct them. For that I do apologize. It's a difficult spec to balance since part of its design is to have large crits and stuns, which have obvious PvP implications. We are pretty confident this will not nerf pallies into the ground as I facetiously promised yesterday, but if we overdid it, we'll be happy to back off some of the changes.
On the other hand, maybe we'll see fewer BGs with 20 paladins on the opposing side and can get some reasonable feedback on all the other classes in the game.
A little more on the changes to Art of War and Righteous Fury (from the same thread)
Art of War was NOT majorly buffed. The damage should remain the same over time, but fewer gigantic crits. It will be something like +4 / 8% damage (instead of +10 / 20% crit), which should be the same overall assuming a crit rate of around 40%.
Righteous Vengeance was majorly buffed to make up for the Divine Storm nerf. It should end up at something like 10% of the crit damage each tick for 4 ticks of 2 seconds each (+40% and 8 sec total).
So basically, AoW will not boost crit damage as signficantly but overall damage for the affected abilities should remain the same. Righteous Vengeance though... if it rolls it's an extremely nasty talent. Nasty in a good way.
The change to Divine Storm is a shame because it fits in so well to the Paladin mold. And it was clearly better than Whirlwind. Now, though it's still a very nice talent, it's still a little disappointing. Giving it a minor coeff like CS would be nice.
I'm still a little surprised that Divine Shield isn't going to be looked at. Still, perhaps given the number of nerfs it undergone over the years another one would feel they've gone a little too far. If there are any further changes I'd expect that skill to be the first one looked at.
EDIT: I just want to be clear. Nothing we've seen thus far will make me stop playing my Paladin in Wrath, nor discourage me from speccing Ret at this time. For the full impact we are all going to have to wait for a little while and see what we're like at 80, only then will we be equipped to make a full Judgement.
