Priests are commonly considered one of the standard healing classes in World of Warcraft, as they have two talent specs that can be used to heal quite effectively.

Their Holy tree includes talents which strongly boost the healing done to their allies, including spells that can be used to heal multiple players at once, such as (Spell #48089). The Discipline tree, while still capable of significant raw healing output, focuses primarily on damage absorption and mitigation through use of (Spell #48066) and procced shielding effects. Priests are also capable of very powerful ranged damage with their unique Shadow abilities, and upon entering Shadowform will see a significant increase in their shadow damage while losing the ability to cast any Holy spells.

• While the Discipline talent tree is commonly used for healing, it also contains some powerful talents that can boost the priest's Holy damage, though Shadow spells and abilities should be used primarily for DPS.
• Priests provide of the most appreciated buffs in the game - (Spell #48161), which grants an indispensable stamina buff to everyone in the raid. They can also buff both (Spell #48073) and (Spell #48169)!
• Shadow priests are an excellent utility class for any raid, providing the much-loved Replenishment buff to boost mana regeneration and can even heal their own party with Vampiric Embrace!
