Stat Priorities
Stat Rankings
Item level over all stats, due to Guardian druids having significant gains from Agility, Armor, and Stamina increases.
For a decent mix of defense and damage, you can use the following stat priority to compare similar ilvl pieces:
Item level > Haste > Vers > Crit > Mastery
As always though, if you are looking for the exact offensive value of these stats you should sim yourself.
Stat Outline
Agility affects all attack power scaling abilities, notably ironfur’s armor bonus scales off your agility.
Haste reduces your GCD and the CD of Mangle, Thrash, and Frenzied Regen.
Crit provides dodge.
Mastery increases your maximum health, healing received, and attack power.
Versatility increases the gains from a lot of your damage and self-healing such as After the Wildfire, Ursoc’s Fury, and Elune’s Favored, on top of granting additional damage and damage reduction.
Races
No race has a massive advantage over the others; that being said, the strongest would likely be Highmountain Tauren (Horde) with their uncapped AoE CC, or Night Elf (Alliance) thanks to Shadowmeld.
