Since Armor hits diminishing returns, while AD scales purely linearly, in theory, Flat Armor Pen should be better because its gains are logarithmic.

But the problem is that Flat Armor Pen comes only in small quantities compared to what you can build as Flat Armor. So the actual increase in damage isn't all that great. It'll wreck squishies no problem, but it's pretty useless against anything else.

With AD, at least, lets Renekton take advantage of his high AD scaling.
