I can't really speak all that well to pulling all of SM following the patch but I have noticed my pally being a bit tougher to kill post patch. He's only 66 at the moment but just running around Hellfire I was impressed by the numbers of mobs I could tackle all at once.


If you'll excuse the length of the following, it's a summary of his talent trees (more or less, I reconstructed it from memory because WoW Armory doesn't have his talents updated):


Holy (0 points)
None

Protection (51 points)

5/5 Divine Strength
5/5 Anticipation
3/3 Improved Righteous Fury
2/5 Toughness
2/2 Divine Guardian
3/3 Improved Devotion Aura
1/1 Blessing of Sanctuary
5/5 Reckoning
2/2 Sacred Duty
3/5 One-Handed Weapon Specialization
1/1 Holy Shield
3/5 Ardent Defender
3/3 Redoubt
3/3 Combat Expertise
3/3 Touched by the Light
1/1 Avenger's Shield
2/2 Guarded by the Light
3/3 Shield of the Templar
1/1 Hammer of the Righteous

Retribution (6 points)

5/5 Deflection
1/3 Heart of the Crusader


I think it's just a matter of adjusting to the new Pally mechanics. Using the new Judgement of Light I get back double what I used to using both Seal and Judgement. Popping Holy Shield as often as you can and perhaps using Devotion Aura will definitely keep your mana up and damage down.
Let me know how that works. I was planning on using my own Pally to start software dual-boxing.
