Pretty much copied and pasted from the Shaman thread:
From pre-patch Gruul to post-patch, I went from:
926 DPS ->
728 DPS.
This is with:
-Drakefist (Crusader) + Gladiator's Cleaver (Mongoose) and Hourglass of the Unraveller; to
-Dragonmaw (nothing yet) + Gladiator's Cleaver (Mongoose) and Romulo's Poison Vial.
Other than that, the rest of my gear was exactly the same. Both times I was completely unbuffed with no DPS pots/food and with BS/LoTP.
I gained a bunch of stats from the patch (my hit went up over 25% without me even stacking it), but my DPS still dropped by ~200 on Gruul. The ratio of WF procs to white hits roughly halved. Gruul obviously isn't the best fight to test things on (and my UI was also not as fine-tuned as it could've been), so I'm not ready to quit my shaman just yet.
