Stat Priority (5.4.8)
Stats are the core of your character and how you choose to balance those stats will greatly impact the effectiveness of your Restoration Shaman. Use this guide to select the stats that are the most important for your Shaman and learn how to prioritize those stats to optimize your performance.
Spirit > Intellect > Haste (Breakpoint) > Crit > Mastery > Haste (Past Breakpoint)
Spirit Increases the rate of your Mana regeneration. Spirit is the best stat for Mana efficiency. Only stack enough Spirit to to have just enough Mana for an encounter.
Intellect Increases the power of your heals and slightly improves your spell critical chance.
Haste Decreases cast time, GCD, and speeds up HoT ticking. Assuming normal raid buffs and Ancestral Swiftness, the 1st breakpoint is at 871 Haste Rating from your gear and adds 1 extra tick to Riptide, Healing Rain, and Earthliving Weapon. The 2nd breakpoint is at 3764 Haste Rating from your gear and adds 1 tick to Healing Tide Totem and a 2nd tick to Healing Stream Totem. The 3rd breakpoint is at 5676 Haste Rating and adds a 2nd additional tick to Riptide.
Crit Increases the chance for direct heals and HoTs to crit for additional healing. Also, thanks to Resurgence, critical heals return Mana.
Mastery Mastery Deep Healing increases the strength of your heals against targets based on their health. Lower health targets received additional healing. You only want to stack Mastery to 50% total buffed or about 5400 Mastery Rating from gear.
