SimulationCraft have a preliminary pre-raid DPS simulation for Vault of the Incarnates up on their site. Check out how your spec performs in a simulated Patchwerk-style environment before the raid opens!
DISCLAIMER: The simulations are a work in progress and for actual logs, we’ll need to wait for the raid to open on December 12. The simulation has been conducted using a Patchwerk boss fight and character templates with an average 422 item level.
Not all specializations have been implemented yet.
SimulationCraft is open source and you can contribute to making it better!
