Season 9 has started and the PVP vendors have finally opened for business, so it’s time to gem and reforge your equipment. With the removal of Attack Power gems, Agility is now the undisputed king of stats for a rogue, but the secondary stats you should be looking at reforging to depend on your spec.
Reforging for Subtlety
Getting your Haste as high as possible should be your objective with reforging for a Subtlety spec. The extra energy regen works out better than the currently pitiful Crit rating, so can be substituted for Mastery, Crit, Hit and Expertise on your equipment. If it already has Haste as a secondary stat, Mastery is about as good as you’re going to get (unless you’re under the hit cap of 5%).
Reforging for Assassination
Mastery, Mastery and Mastery. If you’re going to play your rogue like a tunneling warrior, you want your envenoms and poisons to hit as hard as possible. Potent Poisons turns 1 point of Mastery (requires just under 180 Mastery rating) into 3.5% extra poison damage. Any unwanted secondary stats on your equipment can be swapped to Haste or Hit rating.
Stamina + Agility: Shifting Demonseye & Shifting Nightstone
Hit: Rigid Ocean Sapphire & Rigid Zephyrite
Hit + Agility: Glinting Demonseye & Glinting Nightstone
Spell Penetration: Stormy Zephyrite & Stormy Ocean Sapphire
Gemming for spell penetration shouldn’t be a major concern – a cloak enchant and a gem (in either the gloves/leg/belt socket for the bonus) gives 108 – 120 penetration, which should make a difference to your raw poison damage.
For Assassination specs particularly, Enigmatic Shadowspirit Diamond is useful to help reduce being kited. The Effulgent Shadowspirit Diamond is a viable choice for increasing survivability, though if you’re looking for sheer luck-based potentially game-breaking fun, Destructive Shadowsprit Diamond is the way to go. The 10% reduced stun/fear effect gems are probably not worth taking – stuns have been nerfed more than enough to worry about, and fears can hopefully be dealt with by your dispeller.
For raw stats, the 54 mastery from the Fleet Shadowspirit Diamond is currently the best you can get (especially for Assassination rogues).
