Priest Builds, Updated For Patch 5.2

News:

Patch 5.2 has been released, here are some of the changes that directly effect priests:

-The amount of healing done by Flash Heal, Binding Heal, Renew, and Prayer of Mending have been reduced by 20%.

-Spiritual Healing is a new passive ability obtained by Discipline and Holy Priests at level 10. This ability increases the amount of healing done by Flash Heal, Binding Heal, Renew, and Prayer of Mending by 25%. For Holy and Discipline Priests, there is no decrease to the amount of healing done by those four spells.
-Evangelism stacking effect now also increases the healing of Penance.
-Halo will no longer hit enemies that are in Stealth.
-Angelic Bulwark can no longer be dispelled.
-Dominate Mind now has a 1.8-second cast time (was 2.5 seconds).
-Angelic Feather now has a 6 second duration (was 4 seconds).
-Focused Will is now a passive for Holy Priests, as well as Discipline Priests.
-Power Word: Solace has been replaced with a new talent: Solace & Insanity

-For Holy and Discipline, Power Word: Solace replaces Holy Fire. It deals the same damage, and interacts with other spells and abilities in the same manner but does not trigger Atonement, is instant, costs no mana, and restores 1% of maximum mana on each cast. Damage dealt by Power Word: Solace will heal a nearby friendly player within 40 yards of the target for 100% of the damage dealt (50% when healing the Priest).
-For Shadow, this ability causes Mind Flay to gain the Insanity effect on a target affected by Devouring Plague. Insanity increases the damage of Mind Flay by 33% per Shadow Orb consumed.

-Holy Fire is now an instant cast ability.

-Power Infusion now increases the Priest's damage by 5% in addition to current effects.

-Phantasm no longer makes the Priest untargetable by ranged attacks, and the movement impairing immunity effect is now 5 seconds (was 3 seconds).

-Psyfiend belonging to an individual Priest will no longer cast Psychic Horror on the same target twice.

Discipline

-Mastery: Shield Discipline now also increases all healing done by a lesser amount, but the bonus provided by Mastery has been reduced by 36%.

-Penance damage and healing has been increased by 20%, now a cooldown of 9 seconds (was 10 seconds), and has a range of 40 yards for both friendly and hostile targets (was 40 yards for friendly and 30 yards for hostile targets).

-Focused Will now reduce damage taken by 15% per stack, with a limit of 2 stacks.

-Spirit Shell can no longer be dispelled and now provides an absorb shield equal to the average healing and absorb of the triggering spell, including criticals and Divine Aegis.

-Rapture now reduces the cost of Power Word: Shield by 25% and provides mana equal to 150% (was 200%) of the Priest's Spirit, but no longer benefits from Spirit provided by short-duration bonuses.

-Divine Aegis now causes critical heals to apply an absorb shield on the target for 100% of the amount healed instead of healing for twice as much. In addition, it grants Power Word: Shield a chance equal to the Priest's critical chance for the shield to absorb twice as much damage.
