Then you stack health. Penetration and percentage reduction are pointless against someone with no armor, and the lack of AD they give compared to high-end AD items like BT means the user simply won't burn through your health pool fast enough.

The nerf to the penetration and the fact that its been made unique helps reduce it's prevalence, though.
