It is fine to build ArPen in your runes, I just don't care for it. I feel like +15 AD is better, after the Season 2 masteries gave us a %pen option.

If you go for the full +25 (plus 6 from masteries) you basically are doing true damage to opposing carries for a while, even if they have flat Armor seals. That's kind of nice, since normally your damage would get reduced to about 80% or so, but that's not double, and minions don't really have much Armor so it also doesn't help with last-hitting. I don't know about you, but I don't find it easy to last-hit with only ~53 AD on Ezreal.

Lategame, the flat ArPen doesn't matter. +25 isn't enough to deal with Armor stackers, that's where you need Last Whisper, which combines with your mastery bonus for 46% penetration. Flat AD also helps a little bit with the damage on Trueshot Barrage, for what that's worth.

I'd agree with the above anon: you probably only want ArPen Marks, not Marks and Quints.
