the patch

Well it's certainly worth a look. After a long long time in Combat Daggers, Cat is now 51/5/5 Mutilate. Even on the first night using the spec (I've never used Mutilate at all) she still pulled a clear second on the meter in a quick-pace 2 hour Kara clear tonight. I'm feeling it's a good spec!

Her current spec is pretty close to the draft cookie cutter 51/3/7 Mutilate.

• Mine takes 1/1 Vigor, 2/2 Quick Recovery and 2/3 Master Poisoner, but
• Cookie takes 2/2 Murder and 3/3 Turn the Tables instead.
• Cookie drops 2 points in Dual Wield Specialisation to pick up the missing 2 in Relentlesss Strikes.

I'm not sure about the cookie cutter decisions. Murder might be useful in levelling, but is it better on boss fights than say the 2/3 in Master Poisoner? 4% increased damage against certain bosses, vs 2% extra crit chance against all but poison-immune bosses? Would like to see the mathcraft on that.

I can see the attraction of Turn the Tables over Vigor. But Quick Recovery looks good for boss fights, where you're often taking splash damage - 20% less mana used on you. 4% crit chance on finishers is not that super when you're probably going to be rotating SnD and Rupture (which don't crit) with maybe Envenom and Eviscerate which can crit. But one of those will get the benefit of Cold Blood, so hanging onto 80% of the energy on failed finishers (which mean they can be immediately repeated) seems a good bet.

Giving up 13% of your offhand damage to get an additional 8% chance to get 25 energy on a finisher doesn't seem worth it to me. Again, the mathcraft will decide.

*EDIT*

Right, I plugged the numbers into the Rogue DPS Spreadsheet in Cat's current gear.  On the Assassination tree talents, it's a no brainer.  Cookie cutter is clearly better than the build I chose.  Mea culpa.

On the Combat and Subtlety talents, we were both wrong.  The optimum build is actually 4/5 Dual Wield Specialization and 4/5 Relentless Strikes.  However, there's only about 10DPS in it over all three builds.

Looks like I'm up for a respec!
