Stat Priorities
Single Target and AoE Stat Ranking
Mastery >= Versatility > Critical Strike > Haste
Stat Outline
Agility: Increases attack power and damage.
Critical Strike: Chance to do double damage and apply Find Weakness when you Crit with Backstab and Shuriken Storm.
Mastery: Increases the damage of all your finishers.
Haste: Increases energy generation, bleed tick rate, and attack speed. We run a bunch of energy talents, so it is rarely an issue which is why Haste is typically quite bad for us.
Versatility: Simple flat bonus to damage done and reduction to damage taken.
Races
As Horde I recommend: Orc or Blood Elf
As Alliance I recommend: Dwarf, Void Elf or Night Elf
Enchants
Cloak: Chant of Winged Grace
Chest: Crystalline Radiance
Bracers: Chant of Armored Avoidance
Legs: Stormbound Armor Kit
Rings: Cursed critical strike (best to sim it for your own character)
Boots: Defender’s March
Weapon: Authority of the Depths
Gems
Culminating Blasphemite (unique gem) primary stat + critical effect.
Basically how the new gem system for the unique gems work is that you want different coloured gems to enhance the effect so it's really a sim question for your own character, but generally any combo of the non Haste gems would be what you should be looking at. Would be a combo of these.
