Armor penetration makes you anti squishy, not anti tank.

The more armor you have, the less armor you get per point, meaning that armor pen will increase your damage to squishy targets more than to tanks. Last Whisper/Madreds bloodrazor/void staff are good anti tank items and champions with similar effects (Kog'Maw comes to mind)
