Rogue changes in patch 3.0.3

Although not a ton happened to Rogues in this latest patch, we at WoW Insider like to keep our coverage well-rounded, so let's run down the Rogue patch notes.

• Combat Potency now only works on auto-attacks (i.e. not Shiv). I think we can agree that all the shivving was getting pretty silly.

• Fan of Knives is castable if you don't have a target, looks prettier, and no longer plays an impact on the caster. It also benefits from Find Weakness, and its cooldown was reduced to 10 sec.

• Instead of making the rogue untargetable, Killing Spree now causes all players to lose targeting on the rogue and causes the rogue to be unstoppable during its duration.

• Riposte's effect duration is no longer reduced by effects that reduce disarm duration.
  

• Shadow Dance no longer increases the cooldown on various abilities that require stealth (Sap, Garrote, Ambush, Cheap Shot, Premeditation, Pick Pocket, and Disarm Trap). Feel free to Ambush as much as you have energy for, but don't get too attached to cooldown-free swirly ball Disarm Trap; that's getting nerfed for sure.
  

Overall, it's buff time in Rogueville, as it seems to be for nearly everyone else. The Combat Potency change is essentially a bug fix. FoK's cooldown was cut by two thirds, and you can't argue with a prettier effect. I'm not really sure what to think about Killing Spree's change. I guess it means you can still take damage, if the opponent can manage to target you, but I don't see it as a big deal. And I hear many players are still not particularly impressed with Shadow Dance, but I would expect Ambush's numbers to add up pretty quickly. Have any beta players played with this new version?

Update: missed one: Glyph of Shiv replaced with Glyph of Vigor, which gives 10 more extra energy if you have Vigor.
