Here we will cover all of the new Holy and Discipline talents that will be accessible when the patch becomes live. Not only that, we've offered up some suggestions on different builds to remain raid viable at least to the rare few guilds that are still raiding.
   Here is a quick run down of the new talents we get access to.
   Discipline:
   Twin Disciplines replaced Wand Specialization. Most PvE Priests ought to strongly consider this talent as 5 ranks.
Improved Inner Fire improves the strength of Inner Fire. Definitely want to pick this up if you're investing points into Discipline. It is 3 ranks.
For Aspiration, cool-down reduced on Inner Focus, Power Infusion, Pain Suppression and Penance by 20% when fully talented. It is 2 Ranks.
Rapture restores up to 2.5% of your maximum mana each time you cast a Greater Heal, Flash Heal, Penance, or whenever your Power Word: Shield absorbs damage and when Divine Aegis activates. It is 5 Ranks.
Divine Aegis–Did you crit heal? Take 30% of whatever you crit heal for and watch as that amount of damage gets absorbed on the next blow. Yes, it literally does create a mini-bubble around players. It goes hand in hand with the damage mitigation philosophy of Discipline which is 3 Ranks.
For Grace, your direct heals such as Flash Heal, Greater Heal, and Penance will bless your target with a buff called Grace. It reduces the damage done by 1% and the healing received by the target increases by 2%. The effect is able to stack 3 times. I guess when it's fully operational; it'll reduce damage done by 3% and increase healing received by 6%which is 2 Ranks.
Borrowed Time – Makes your next spell after casting Power Word: Shield faster by 25%. Not only that, it increases the amount of damage absorbed by 40% (assuming full ranks). Yes, it does stack with Improved Power Word: Shield which is 5 Ranks.
Penance – Channeled spell. Either damages an enemy or heals an ally every second for 2 seconds. 30 second cooldown means it won't be used every chance, which is 1 Rank.
Holy:
Desperate Prayer was formerly the Dwarf and Human racial. It is now the 11 point talent where Holy Nova used to be. It has a 2 minute cool-down and it now costs mana (as opposed to a 10 minute cooldown where it didn't have mana costs to begin with). It is 1 Rank.
Surge of Light – it is 50% chance that your next spell crit will allow your next Smite or Flash Heal to become free and instant cast. Unfortunately, it means it can't crit. 2 Ranks.
Empowered Healing – Greater Heal becomes 40% stronger and both Binding and Flash Heal heals for 20% more. Percentages are based off of bonus healing effects. It is 5 Ranks.
Serendipity – Definite must have for the PvE Priests. If you overheal while casting Greater or Flash Heal, you'll get 25% of the mana cost back. It is 3 Ranks.
Improved Holy Concentration combines with Holy Concentration for a 45% chance to get Clearcasting (a free Flash Heal, Binding Heal, or Greater Heal). Not only that, but the spell haste for the next 2 Greater Heals, Flash Heals, or Binding Heals is increased by 30%. They look like 2 charges. It is 3 Ranks.
Test of Faith – Overall healing is increased by 6% which increases your spell critical chance by 6% on friendlies below 50%.3 Ranks.
Divine Providence – Circle of Healing, Binding Heal, Holy Nova, Prayer of Healing, Divine Hymn, and Prayer of Mending have their healing strength increased by 10% (fully talented). It is 5 Ranks.
Guardian Spirit increases healing received by the target by 40% and prevents the target from dying by sacrificing itself. If that happens, the targets health shoots back up to 50%. It is 1 Rank.
