Is this information simply not meant to be public, or does it exist somewhere else?
Well, there's the third option, which is we don't know yet.
I know Valera was doing some work a bit back on weapon power, but don't remember if anything came of it. Str, Int, and Ref aren't very important. "Hidden" stats gained with levels do more. Ranged/melee has no difference currently. I don't think there's been much in the way of finding enemy stats.
In conclusion, there's not much that I know of that we have actual numbers on.
You could always go figure it out yourself.
