I don’t have a lot of time to comment on these changes at the moment, but here they are, from mmo-champion.
All paladins auras had their range extended from 30 yards to 40 yards.
Holy

Sacred Shield now cannot be on more than one target at any one time.
Infusion of Light no longer has a chance to reduce [...]

General
Players at maximum level will now be able to visit their trainer to pay a one-time fee and access the dual talent specialization feature. (1000 gold)
A new Gear Manager feature has been [...]

This is truly awesome! The first we’ve officially heard about dual specs and positive confirmation that it will be in the next patch (3.1). All of the information is very new and will take some time to digest. Here is the Q&A source. Below is the quoted text.
Talent Dual Spec Q&A with Ghostcrawler
With the next [...]

Here are the gems and enchants that are relevant to tanking. This is from my limited prot pally point of view. I don’t know what gems or enchants the other tanks need but I’m sure that most are the same.
Enchants
Head

Arcanum of the Stalwart Protector revered with Argent Crusade

Shoulders

Greater Inscription of the Pinnacle exalted with Son’s [...]

The announced changes seem to be prot-pally related, for the most part (source).

Blessing of Kings – this spell is now a base ability trainable by all paladins.

Blessing of Kings being a baseline talent is AWESOME. This is something the pally community has been raving about for ages.

Exorcism – this spell now causes damage to [...]

Last night, I was a part of a 25-man OS pug. I was uber-buffed – over 5k AP and just over 36% crit. Here is a screen shot I took just before were going to attempt Sarth.
Here are some other screenies of Dessara in her prot gear, with the Red Sword of Courage and it’s [...]

I’ve been very busy since my last post. Between the time 3.0.8 went live and now, I’ve been running heroics and leveling jewelcrafting and also doing somethings I never thought I would do – raid 25-man Naxx and 25-man Obsidian Sanctum.
The 25-man Naxx/OS runs were very fun. I was the 3rd tank or the off-tank [...]

The only thing that I didn’t like about tanking H Gundrak was that I felt I has too little health. Then I remembered I could make one of the stamina-oriented trinkets that jewelcrafters can make, the Monarch Crab and I would still be above the raid crit cap of 540 defense!
I added a Solid Sky [...]

I put on my prot gear this morning, got a Frosthide Leg Armor kit filled in the empty gems slots green gem slots I had and logged out before work. When I left home, I was sitting at just under 20k health.
I want my health to be 24,000 unbuffed.  I’ve been looking over the spreadsheet [...]

I created a spreadsheet over at Google Docs so that I can just modify the spreadsheet as my situation changes and  this post will be automatically updated as the spreadsheet is changed. Seems simple and efficient, right?
This is all pre-raid gear since who know when I’ll step foot in Naxx, if ever. There are also [...]
