Updated III: Paladin PTR Patch 3.0.8 Notes.

Update 3: Item updates on the latest PTR build.

Glyph

* Glyph of Flash of Light - Your Flash of Light has an additional 5% critical strike chance. (Old - Your Flash of Light heals for 50% less initially, but also heals for 140% of its inital effect over 12 sec.)
* Glyph of Holy Light - Your Holy Light grants 10% of its heal amount to up to 5 friendly targets within 20 yards of the initial target. (Up from 10 Yards)
* Glyph of Hammer of Wrath - Reduces the cost of Hammer of Wrath by 100%. (Old - Increases the range on Hammer of Wrath by 5 yards.)


Items

* Libram of Reciprocation now gives Your Judgement of Command spell a chance to grant 173 critical strike rating for 10 sec. (Old - Haste Rating)

The value of the new Libram of Reciprocation vs the PvP Librams (which grant an AP buff via Crusader Strike) is very much dependant on Proc rate. It is definitely not the pure suck it was, however it seems a little bizarre for a ostensibly PvP Libram to be provided by Heroic/10-man PvE tokens and yet no decent PvE Libram can be obtained from the same source.

The Glyph changes are all awesomsauce, though how long the HoW one remains in the game remains to be seen.

Update 2: New Patch Notes on the official site (more up to date than the ones that came with the PTR download, but don't feature all of the datamined information below). The new taunt spell is in these patch notes but MMO-Champion hasn't logged it yet.

Hand of Judgement renamed Hand of Reckoning and is available at level 16 from the trainer. [Much better name, those I'm not sure that the 'Hand' label really fits].

Update: Datamined changes from MMO-champion included.

The latest PTR patch notes are now posted on MMO-champion. The patch designation is 3.0.8 (no, I don't have any clue why it has this numbering). The changes are pretty much as expected for Paladins:

Paladin Notes:

Skills
Protection

* Divine Protection The penalty has been removed.
* Divine Shield The penalty has been changed so that all damage done is reduced by 50% in place of an attack speed penalty.
* Hand of Protection now Cannot be targeted on players who have used Avenging Wrath within the last 30 sec sec.
* Avenging Wrath now Cannot be used within 30 sec sec. of being the target of Divine Shield, Divine Protection, or Hand of Protection.
* Hand of Reckoning(NEW): Available on trainers at level 16. It’s a 30 yard range taunt that causes Holy damage.


Retribution

* Judgement of Wisdom now give each attack a chance to restore 2% of the attacker's base mana. (Old - 1% of the attacker's maximum mana)
* Judgement of Light now also procs from ranged attacks.
* Seal of Blood now deals 27% of normal weapon damage. (up from 22%)
* Seal of the Martyr now deals 27% of normal weapon damage. (up from 22%)

The Seal of Blood/Martyr changes are both tooltip clarifications. The 22% value never made it to Live; it has been 27% since 3.0.1 hit the servers.

Talents
Retribution

* Seal of Command now Gives the Paladin a chance to deal {0.45*Min Weap Damage+0.45*0.23*SpellPower} to {0.45*Max Weap Damage+0.45*0.23*SpellPower} additional Holy damage. (Old - Didn't scale with Spell Power)
* Vengeance now stacks up to 5 times. (Up from 3)[I don't normally make retroactive changes to these sorts of posts, but as this is such a big change I guess it's warranted. Vengeance, as of PTR build 9464, once again only sstacks 3 times.]

There is some doubt over whether the SoC change is tooltip or a real change. Smart money is on it being a tooltip change. As the Vengeance change is undocumented you should be aware that it may be 'un-buffed' at any time. Hopefully this won't be the case, but it is a PTR after all.

Holy

* Judgements of the Pure now Increases the damage done by your Seal and Judgement spells by 5/10/15/20/25%, and your Judgement spells increase your casting and melee haste by 3/6/9/12/15% for 1 min.

Protection

* Sacred Duty no longer reduces the attack speed penalty on Divine Shield and Divine Protection. Rank 2 now increases total stamina by 8%. (Up from 6%)

--

* Glyph of Holy Light now affects friendly targets in a radius of 10 20 yards (previously 5 yards, see top).

(Source)

Curiously there is no mention of the new ranged taunt spell, Hand of Judgement, nor of bug fixes to Judgement. The latter tallies with them not knowing just what is causing the bug... I have my suspicions.

Large boost to Vengeance, allowing it to go up to 15% again (though stacking x5 rather than x3). I'm not sure if the Seals are tooltip clarifications to current values or genuine buffs (most believe it is the former), but I'm not one to look a gift horse in the mouth. Either way it's a good change, and they'll be some frantic calculations going on to re-weigh the pro's and cons of SoC and SoB wrt the Spell Damage.

Still no news on whether or not Forbearance remains in the game. As I mentioned before it seems rather hamfisted to keep it in with the new mutual lock-out, but you never can tell.

The change to Glyph of Holy Light *may* be nice. Even an increase to 10 yrds would be of huge significance.

There may well be features in the Build being deployed to the PTR than are listed in the patch notes, so keep your eyes open for further undocumented changes.
