The Holy Priest in WoW Classic is the archetypical healer and that's about all you can say really.
The Holy Priest is WoW Classic's Healer supreme, both in PvE and PvP. They have a broad range of abilities to heal an entire group and keep themselves alive. What's more, they have at their disposal many buffs for their allies making Holy an indispensable raider. On the other hand, Holy remains less powerful than the Shadow Priest who has the ability to heal extremely well in restricted groups while being able DPS, contrary to the Holy Priest.
In PvP, the Holy Priest is quite comfortable and is an excellent Healer but will often be competing with the Shadow Priest.
This build is oriented purely towards healing and is recommended for all Priests wishing to progress in new content. It's one of the best Raid Healers and has few mana problems, making it particularly indispensable in the vast majority of groups.
Stats to prioritize
Healing Power> Spirit> Mana every 5 seconds> Intelligence> Critical Spell Strike> Spell Damage> Stamina
There is no priority, strictly speaking, as a healer. However, here are the spells you should use as well as in what situations. Respect the rank of each proposed spell, mana is a real problem for WoW Classic, using a lower rank spell allows you to save mana without sacrificing healing.
Prayer of Healing: Do not overdo it, it is a very expensive spell. Use the different ranks of this spell to heal the entire group if it has suffered too much damage (do not use Rank 5 while the group has lost 10% HP for example).
Power Word:Shield: Use this spell only in anticipation of significant damage to a target, usually the Tank. Always use the maximum rank of this spell.
Greater Heal: This is your heal in anticipation of heavy damage. If you know that a target will take heavy damage, pre-cast this spell to raise the target's health at the same time that it takes damage. Prefer Rank 3 for most cases, and Rank 5 for really monumental damage.
Flash Heal: Only Rank 7 of this spell will be helpful. Throw it as soon as a target suffers unexpectedly large damage, but do not spam it, or you'll end up OOM fast.
Holy Nova: Very effective in raising the health of your group but requires a good positioning. Always use the maximum rank.
Renew: Very useful when you have to move, always use the maximum rank of this spell.
Heal: This is your main healing spell, you can spam without much fear of being OOM.
Inner Focus is a powerful healing CD that can (and must) be used in an emergency during major damage phases on any of the Tanks or the entire group, in order of priority, Prayer of Healing, Greater Heal or Flash Heal.
Prayer of Fortitude
The Prayer of Fortitude is the same as Power Word: Fortitude but on an entire group and therefore makes the Priest indispensable in any type of content. This is a considerable time and mana gain, especially in raids, but it has a slight cost: a sacred candle per cast.
Prayer of Spirit
The Spirit Prayer is the equivalent of the Divine Spirit but on the whole group and therefore makes the Priest indispensable especially in raids. This is a considerable time and mana gain, especially in raids, but it has a slight cost: a sacred candle per cast.
Best Race For Holy Priest
The real interest of the Undead is the Will of the Forsaken which is excellent in PvP. Apart from that, Cannibalism is interesting in levelling. The only interest they have in PvE is that they have a base of slightly more points of Intelligence and Spirit than other races.
Priest unique skills: Devouring Plague and Touch of Weakness.
The Berserker is rather powerful for Holy, it makes Troll one of the best races if you plan to play Priest. Special mention for Beast Slaying which is useful for leveling or farming.
Priest unique skills: Hex of Weakness and Shadowguard
The Dwarf's Stoneform is a serious asset in PvP, especially against Rogues. Frost Resistance is also great against your nemesis: the Frost Mage.
Priest unique skills: Fear Ward and Desperate Prayer
The Human has serious assets making it potentially better than the Orc depending on the chosen build: Mace Specialization and Sword Specialization, Diplomacy is also great when grinding reputation, and Perception is very usefull in PvP.
Priest unique skills: Desperate Prayer and Feedback
World of Warcraft: Classic has a number of races to choose from, and making that choice has long-term consequences. You don't want to regret your choice later, so we've broken down the races in our tier list for WoW: Classic.
The Engineer is the best choice by default as it's great in both PvE and PvP. From Goblin Sapper Charge to the Arcanite Dragonling to the Dense Dynamite, everything about this role will always be useful!
If you do not opt for Engineering, then the Enchanting profession will certainly delight you since it will allow you to make your own enchantments by disenchanting the items you get on the way and in raids/dungeons, but also the ones you make for yourself from Tailoring.
Tailoring is a must-have for the Mage: it allows you to craft pre-raid armour pieces of unparalleled power, including the Robe of the Void. This is the quintessential profession of the Warlock.
