Discipline

In the Cataclysm, the focus of discipline priests turns to preventing,WoW Gold absorbing, and deflecting damage, no longer PvP-friendly and great single-target healers. This changes makes priests a great tree for those who prefer a more proactive approach to party healing.

In the first tier, Twin Disciplines now also increases the damage absorbed by Power Word: Shield. The new tier three spell, Atonement, introduces an interesting twist to healing: when you deal damage with Smite, you will instantly heal a nearby friendly target for a percentage of the damage dealt. No longer will Priests be related to "Whack-a-Mole" duties!

The new tier five talent, Archangel, offers a little instant mana return and allows you to channel the Penance spell while on the move. This is a definite benefit to Discipline Priests. Disciple is definitely shaping up to be one of the best WoW Gold Priest builds with the arrival of Cataclysm.

Holy

With the advent of talents such as the re-designed Searing Light in the first tier, holy priests may be more viable dps-ers in Cataclysm than ever before. Divine Accuracy in the second tier provides some much-needed hit for Priests, and Empowered Healing is now relocated here from the eighth tier.

There is a new added tier seven talent, Choir Leader which adds a self-heal to the Priest's Divine Hymn spell while reducing the time it takes to channel it. The most interesting talents in this tree, however, fall into the lower tiers. Body and Soul and Chakra, both talents in the eight tier, look particularly interesting. Increasing a target's movement speed and a boost to Smite dps from three successive heals point toward the Holy Priest as a utility class rather than a pure Healer.

Shadow

Players might expect some type of healing ability to be bestowed upon the Shadow Priest. Unfortunately, the new and improved Shadowform, which has always restricted the caster to non-holy spells, WoW Gold now drops both the threat reduction and the access to Cure and Abolish Disease spells.

In exchange, some of the Shadow Priest's abilities will now apply buffs to the party, increasing spell haste. Other abilities will buff only caster with increased hit, lessened mana cost, or additional damaging abilities. Till now, from players' impressions, the Shadow Priest has fewer choices, fewer "fun" abilities, and the least amount of changes in Cataclysm.

Regarding the changes in Cataclysm for priests, we can always count on changes being implemented, and future patches may indeed bring some more of the love on which Shadow Priests thrive. Here's to hoping.
