New trees, and Mutilate.

As you can see, I've updated all my links to the current talent trees that will be available with the new patch that is to come out, which introduces Dual-Specs and Ulduar.

And here is another spec to consider for you rogues, Mutilate.

Mutilate follows the basic principles like keeping rupture and slice and dice up, but now you also must keep Hunger for Blood active as well. Instead of Sinister Strike, use Mutilate, which means you'll want 2 daggers. Deadly Poison on the main-hand, Instant Poison on the off-hand. Quicker daggers yield better results due to poison procs and focused attacks.
