Holy Priest

Stat Ranking

Int > Mastery = Critical Strike > Versatility > Haste

Stat Outline

Intellect: is your primary stat. It will provide you with Spell Power which will increase the efficiency of your heals.

Mastery (Mastery: Echo of Light): your direct healing spells heal for an additional amount over 6 seconds.

Critical Strikes: double the effects of your healing.

Haste: lowers the cast time on your spells, as well as reducing your global cooldown.

Versatility: increases your damage done, healing done and decreases your damage taken.

Stat recommendations

A big portion of your healing is going to be from your Mastery: Echo of Light, which is why you want to get as much as possible. It is the most mana efficient stat by a large amount.

For Mythic+ you could go for Crit/Haste as you can basically drink as often as you want.
