calcualte monster damage on me?

I think the true problem is the Classes 'Natural Defense' since that will always exist even with 0 W.Def. So I think it'd be best to figure that part of the formula/Equation first before trying to figure out what base damage is, or at least have multiple people post pics of themselves getting hit at various levels with only 0 W.Def as part of the process. I'll be uploading my pics on my Deaviant Art Account under the 'Scraps' title, and I'll post a link in my 'Signature'.
