No, this P/MDrate "defense" isn't what you think. It's a set property of a boss that permanently decreases one's damage by a fixed %. This isn't weapon/magic defense as used in the defense formula in Threaten and other offensive skills. Even if skills reduce PB or any boss's physical defense to 0, you'll only see roughly a 5-10k increase in damage per hit (depending on the class's offensive skill multiplier and when mob w. def is taken into account).

Don't be confused...there's P/MD, and there's P/MDrate.

Is this a confirmed information? (skill ignore % defense does not reduce P/MDrate),
what's your information source? or did you play at KMST/KMS yourself?

Thanks ^^
