There are too many armor pen items in this game.
At this point AD casters are getting dangerously close to dealing borderline true damage without cost.
(duskblade, doesn't have an icon)

Then there's the Precision and Battering Blows masteries.
In addition to all this armor pen and true damage in the meta

? Thats.. 40 armor pen and
gives 45 armor lel
