In terms of selecting a class to participate in, it is recommended that you select one that you enjoy playing above all else. Priests will always be a good choice for questing, dungeons, raids, and PvP. They are also good at healing. In addition to powerful talents such as Pain Suppression and Circle of Healing, both Holy and Discipline trees provide an extensive set of abilities that include Prayer of Mending, Binding Heal, and Prayer of Mending. The buffs they provide are somewhat limited when compared to the output boost provided by Bloodlust, but they more than make up for this with their excellent healing capabilities.

Priest Class Guides and Overview in The Burning Crusade

Despite the fact that Shadow's damage output is not particularly high, they provide support for Warlocks and other casters through Misery and Shadow Weaving, among other things. They also provide a significant amount of regenerative utility to their party as a result of the effects of Vampiric Touch and Vampiric Embrace. Because they share many of the same abilities as a Holy/Discipline Priest, their buff utility is comparable to that of a Holy/Discipline Priest. While playing World of Warcraft Classic, you should consider purchasing some WOW classic TBC gold to give yourself a competitive advantage from the start.

PvE Priest Specs to Consider
When it comes to Priests, choosing the best spec is dependent on the role that is being played, as they can either heal (Holy or Discipline) or deal damage (Shadow). Holy provides a greater healing bonus and raid utility than Discipline, but a number of points will be allocated to Discipline as well. Shadow will deal significantly more consistent damage than Discipline in terms of damage output.

PvP Priest Specs to Consider
When it comes to PvP, Discipline is a fantastic choice because it provides excellent survivability and damage-dealing utility, and the spec as a whole is tailored towards this style of play. Even in PvP, Shadow is a viable option, though their damage and healing may not be as effective as Warlock's damage and healing or as effective as Discipline Priest's healing, respectively.

What is the best priest spec for leveling?
In general, the most recommended spec for leveling up to 70 is Shadow, due to its higher damage output when compared to Holy or Discipline. However, the best spec for leveling up to 70 is dependent on the type of content that you will be doing. However, because Holy/Discipline has a low damage output, it can be a good choice for players who spend the majority of their time in dungeons, questing, and grinding instead. The auction house, as well as the bank, are where you can deposit your vanilla WOW gold TBC. Let us briefly discuss Anduin, who did not play any significant roles.

Specializations for Priests
A total of 61 talent points will be awarded to each class in the Burning Crusade Classic expansion, allowing them to select talents from a variety of trees. However, most builds will place the majority of their points in one tree and only select bonuses from the others. According to whether the player is interested in PvE or PvP content, priests have a number of viable talent combinations to choose from.
Practice: Uses magic to protect allies from being damaged as well as healing them after they have been wounded.
Many of Discipline's talents are geared toward increasing survivability, damage output, mana efficiency, and overall usefulness of the character. In a PvE environment, a Discipline Priest's healing output will be significantly lower than that of a Holy Priest, despite the fact that their overall toolkit is better suited for PvP.
Holy: A healer who is capable of reversing damage on individuals or groups, and even healing from beyond the grave, is a powerful healer.
The Priest's healing abilities, particularly their AoE healing, are greatly enhanced by the talents available in Holy.
Shadow: He employs sinister Shadow magic, particularly damage-over-time spells, to exterminate his opponents.
Talents in Shadow are primarily concerned with enhancing the Priest's ability to deal damage, while also serving as a utility for other casters.

Most races have the ability to become Priests, which means there are a variety of options to choose from, though each race has its own set of unique abilities. In most cases, the 'best' option is not the only one to choose from, because every race-class combination has its own distinct playstyle. The fact that you did not select the optimal racial bonus would have no effect on your ability to perform well in either PvE or PvP content.
The Human Spirit, provided by the Alliance Human, provides a respectable bonus mana regeneration.
The Night Elf provides Starshards, which provide a significant amount of additional damage.
Along with Desperate Prayer and Stoneform, Dwarf provides excellent PvP utility in the form of Chastise (which was previously a baseline Priest ability), as well as Desperate Prayer and Stoneform.
In the form of Inspiring Presence and Symbol of Hope, the Draenei can provide useful group buffs to their allies.
Consume Magic and Arcane Torrent, both available to Horde Blood Elf players, are the best PvE utility spells available.

Undead provides some of the best PvP utility in the form of Will of the Forsaken, as well as Shadow Resistance and Devouring Plague, among other things.
Troll provides Berserking, as well as the powerful PvP abilities Hex of Weakness and Shadowguard, among other things.
As with most classes, there are a variety of options available depending on how much time and effort you want to put into your character and what you want to do with him or her in the long run.
Tailoring grants access to incredibly powerful Tailoring-only armor that will last well into later raid tiers, if properly maintained. When a Priest obtains the Mooncloth Tailoring specialization, he or she can craft and use items such as the Primal Mooncloth Belt, Primal Mooncloth Shoulders, and Primal Mooncloth Robe, whereas the Shadoweave Tailoring specialization allows the Priest to craft and use items such as the Frozen Shadoweave Shoulders, Frozen Shadoweave Boots, and the Frozen Shadoweave Robe. Tailoring and Enchanting are natural partners because Tailoring does not necessitate the use of reagents from a gathering profession.
Enchanting grants access to ring enchants that can only be used by the Enchanter, such as Enchant Ring - Spellpower and Enchant Ring - Healing Power, which are only available to Enchanters. A Priest can also use Disenchant on unwanted gear or items to obtain Enchanting materials, which can be used to make new gear or items.
Herbalism and mining will both provide a reliable source of income as an alternative to Enchanting throughout the course of the expansion.
