Holy Paladin

There are couple different crit "breakpoints" we are trying to reach so stat prio is going to change depending on the amount we have.

• At 30% critical strike (or 25% with the Tier 19 2-piece bonus) our Holy Shock reaches 100% critical strike with Avenging Wrath.
• At 50% critical strike (or 45% with the Tier 19 2-piece bonus) our Holy Shock has 100% chance to crit.

Below 30% critical chance

Below 50% critical chance (or 45% with the Tier 19 2-piece bonus)

Above 50% critical chance (or 45% with the Tier 19 2-piece bonus)

For Dungeons(DPS)

Intellect is our primary stat, it provides us with Spell Power and increases the healing and damage of our spells.

Criticial Strike increases our chance to critically hit with all spells and abilities. Critical Strike is very strong for Holy Paladins as Holy Shock has double the normal critical strike chance which also procs our Infusion of Light.

Mastery: Lightbringer increases effectiveness of our spells on targets closer to us. 

Versatility is a flat-out healing done increase and damage taken reduction.

Haste lowers your global cooldown and your cast time.

Legendaries

Before I go into details about legendaries I just want to say that if you are progressing you should always be looking at the actual usefulness of a legendary rather than raw HPS. The perfect example would be Prydaz, Xavaric's Magnum Opus vs. Ilterendi, Crown Jewel of Silvermoon. For most people on fights like Elisande or Gul'dan the neck will provide more HPS but it is all passive and not controllable healing and it's just adding to our already very strong survival kit , while on the other hand the ring might provide less HPS but it is 100% in your hands WHEN and HOW you benefit from the healing increase, making it far more valuable than the neck, despite it doing less HPS.

During farm it doesn't really matter, you can just have fun and play whatever does most HPS, but when it comes to progression do yourself and your raid a favor and just use whatever will help you actually make your raid live, because ultimately, that is what healers are here for.

Velen's Future Sight 
Very good and extremely versatile legendary, try and line it up with Holy Avenger or Avenging Wrath for maximum effectiveness.  This legendary requires some thought to use well, sometimes best thing to do with it active is to just overheal on purpose and let its smart healing do all the work, other times raw increase in healing is far more valuable, how strong this one is comes down to you and how well you use it.

Ilterendi, Crown Jewel of Silvermoon 
Really good with Judgment of Light. This legendary can potentially increase the healing of your next 3 spells if cast back to back, ideally you should aim to get Holy Shock, Light of Dawn and 1 more cast off with the buff. You have full control of when you get the buff and how useful you make it out to be. 

Maraad's Dying Breath 
Provides great spot healing and great mana efficiency, but provides slightly less throughput than other options and is also unfortunate enough to be in the same slot as Drape of Shame. Effectiveness comes down to how well you use it, since the output it does is 100% in your control. Very good synergy with T20 .

Obsidian Stone Spaulders 
Good legendary that is entirely passive and doesn't require you to do anything extra. Good synergy with Aura of Sacrifice. Strong on fights with tons of AoE damage such as Elisande or Gul'dan. 100% passive and not controllable output.

Chain of Thrayn 
Decent legendary, biggest downside is that talenting into Sanctified Wrath is prefered to make the most use of it and for raiding Judgment of Light is simply better in majority of raid situations. Another thing is that  it makes our already strong wings even stronger which in most cases is going to result in overhealing. Still a decent legendary, easily the best one for dungeons.

Prydaz, Xavaric's Magnum Opus 
Big stat stick that provides you with a very big shield every 30 seconds. A strong item, especially for progress. Should not be paired with Obsidian Stone Spaulders due to anti synergy (with shoulders you want to be losing health and neck stops that). Selfish legendary  that increases our survivability (Which is already really strong), it will help keep you alive but it will provide no benefit whatsoever to your raid. While it may do very decent in terms of HPS, in my eyes this is actually pretty weak legendary and I wouldn't even consider it outside of niche situations.

Uther's Guard 
Straight up horrible, 50% duration increase on blessings is in most cases useless, the healing it does is not transferred to beacons and it is not increased by mastery, those things coupled with the high mana cost of Blessing of Freedom makes this item very inefficient. However, if BoP or BoF lasting 50% longer was somehow crucial for your team then this could be of value.

Tyr's Hand of Faith 
Generally quite weak, Lay on Hands is a life saver but other options are just better. Alright for dungeons.

Aggramar's Stride
Provides 0 benefit outside of movement speed and its high item level. Could be used if a fight required constant crazy movement speed but pretty useless otherwise.

Sephuz's Secret 
Great if you can maintain high uptime, useless otherwise. 

General Gearing

Generally any item with high Crit is king when it comes to gearing.

Drape of Shame is amazing and you should try and farm it as high as possible, best in slot cloak by quite a bit.
T19 2 piece bonus gives our Holy Shock extra 10% critical strike chance which is terms of raw output isn't all that great but this set bonus provides consistency with is always desired for progression.
T19 4 piece bonus gives our Infusion of Light an extra charge. Very strong bonus.
When it comes to T19 you want to use helm, chest, legs and then choose between either shoulders or gloves.

Trinkets

Zerotorescue's trinket comparison  (spreadsheet):

Go to the spreadsheet, make a copy by clicking on "copy link", once copied insert your stats and your Artifact weapon. Once done click on trinkets down in bottom left corner, scroll down, insert what trinkets you currently own and what level you have and see how good it ranks.. It is actually very important that before doing all this you insert your own stats as otherwise the results will not be correct.

Races are a lot less beneficial than they used to be, however the best races for Holy Paladin are:

• Horde: Blood Elf (Arcane Torrent)
• Alliance: Dwarf (Stoneform) 

• Neck: Enchant Neck - Mark of the Ancient Priestess
• Cloak: Enchant Cloak - Binding of Intellect
• Rings: Enchant Ring - Binding of Critical Strike

• Sabers eye of Intellect in one slot
• Deadly Eye of Prophecy in all the other slots

You should always use the following consumables to maximize your performance:

• Flask: Flask of the Whispered Pact
• Potions:
  • Pre pull : Potion of Prolonged Power
  • In combat : Ancient Mana Potion or Leytorrent Potion if you can afford to AFK for 10 seconds
• Food: Lavish Suramar Feast or The Hungry Magister 

Optional Consumables

• Rune: Defiled Augment Rune
