Overview
Subtlety is the Rogue tree that changes the most in WoW Forever. The goal: break away from an identity reserved for PvP. 
Thousand Cuts, the new final talent, is tied to Rupture: every periodic tick of Rupture lowers the cost of your next 
Hemorrhage or 
Backstab, up to 5 times. With Rupture always up, that is about 1.5 energy per second.
Quietus, a new talent, adds 10% damage to Sinister Strike, Hemorrhage and 
Ghostly Strike against a target below 35% health. Hemorrhage and Ghostly Strike hit harder with a dagger. Hemorrhage lost its physical damage bonus for the group and instead raises the damage of your Rupture by 15%.
The spec relies on bleeds: it suffers little from downtime, but a boss immune to bleeds gets in its way. It has the highest skill ceiling: keeping Hemorrhage, Rupture and 
Slice and Dice up, and landing Garrote after 
Vanish. Its real PvE value is still to be confirmed at higher levels. At level 20 in the beta, it leads the Rogues in A tier among DPS.

Read the details
Your bleeds keep working when you have to step away, and 
Evasion, Vanish and 
Feint keep you alive. 
Setup always gives you a combo point when you dodge or resist a spell: Evasion becomes partly offensive.
On the other hand, you bring no raid buff, enemies immune to bleeds get in your way, and your energy feels a little slow.
Key spells
Key talents
- The level 20 Ambush build.
- Sap and Blind cost 50% less energy at 2/2.
- One extra combo point, guaranteed, with Ambush, Garrote and Cheap Shot.
- No longer requires stealth, and its combo points last 20 sec.
- Ignores part of the armor and strengthens Rupture.
- Cheaper Garrote and Cheap Shot, and Garrote without having to stand behind the target.
- Backstab can let you use Ambush out of stealth.
Preparation, then Thousand Cuts at the bottom of the tree.
Rotation and priorities
At level 20, like the other specs:
Later on, keep Hemorrhage, Rupture and Slice and Dice up, and open with Garrote after Vanish.
Stats
- 1Agility
- then 2Attack power
- then 3Hit
Order to be confirmed: the exact priority is not settled yet.
No list is established. Aim for Agility, attack power and hit. The order is still to be confirmed.
Leveling
Two level 20 builds. The dagger build, shared by all three specs, with Puncturing Wounds for Backstab. The Ambush build: 
Master of Deception 3/3, 
Opportunity 2/2 and 
Improved Ambush 3/3 in Subtlety, 
Improved Sinister Strike 2/2 and one point in 
Malice. It gives you a strong opener every time you go back into stealth.
Keep your main-hand weapon up to date, and switch to daggers for Backstab and Ambush. In dungeons, 
Sap is risk-free. Wailing Caverns, The Deadmines and Shadowfang Keep have pieces for you.
