I showed earlier that our Krosus model matches real-life logs from top Warcraft players. That makes these simulations incredibly useful because the advice you get is based on real situations. Below is a guide to help you simulate different scenarios to see how it impacts your DPS. You can also take the scenario closest to how you play and generate stat weights from that.
Step 1: Load your character into the simulator
Click this link to go to the simulator. Load your character from the armory, or the addon import.
Step 2: Review your character setup
The left side of the simulator page is all about your character. Click the plus signs to expand sections, like talents. Click on gear in the list to select different gear, relics, or enchants.
