Hey Lujaar, for our reference in figuring out why FT is doing so well for you, would you mind posting a pic of the results pop up on top of the configuration page, much like this following pic:

this way we can see both your parameters and the output. As an aside, i've always said that my calculations for FT aren't nearly as good as my WF ones, because I put more effort into the WF part.
Oh, and one thing to check because it's hung up another poster before - armor mitigation paramater is: 1 = all damage goes through. 0 = no physical damage goes through. So, a mob has 20% armor mitigation, you'd put in .8 for that stat (i named the variable very counter-intuitively)
