PD provides more dps/survivability than LW even if the enemy team builds tons of armor. Remember it adds +30% to your 25% crit chance from IE, as well as 55% attack speed to proc even more crits and 15% speed which enables chasing + escaping.

Compare LW with its 40 AD and 36% armor penetration (36% arpen =/= 36% damage by the way, it will be only around 10-20% dps increase).

IE+PD are basic items that MUST be build first no matter what, only acceptable deviation from this build are vamp scepter, boots, wriggle and boots. Sometimes its even better to build a second PD or BT before even getting LW depending how much you need the extra speed and how squishy the enemy team is.
