@Unevent no, Riot has specifically stated in recent times that a reason they changed from flat Armour Pen. to Lethality was supposed to be for scaling against tanks but it "wasn't achieving the desired outcome" so the they tried buffing it from  Lethality = { Base Lethality × [40%+(60%÷level)]} to  Lethality = { Base Lethality × [60%+(40%÷level)]}, raising the initial amount.

Flat armour pen just for killing squishies is a daft idea, because we already have AD and Crit for that.

Flat armour penetration/reduction makes more sense as something in higher amounts, to go on low AD items, making it good for champions with low AD scaling but high base damage (good in theory for champs designed to be more like tanks).

Instead it is just being used as an alternative to AD in basic functionality.
