I linked this in another thread, but I just want to make sure those of you that have been looking for something like this have it handy.
There are some general instructions on there. Make sure that you're entering each mitigation talent/buff in their own line.
Don't care how you use it, etc. Just download it and let me know if there's anything I should add. Thinking about adding trinkets/greaters with their average mitigation output. Good luck.
