Because I worry about Apprehend late game and I will only be getting a little bit of armor penetration from 1 level, 5%. Those runes are basically for the beginning game ganks on the tank, or anyone else really beefy. But I do see what your saying, I have been thinking about switching them out with speed runes, or just more attack damage, but have not tried it yet.

Pretty good guide! Upvoting. But may I ask, in the runes. Why use Greater quintessence of desolation? You shouldn't be ganking with out Apprehend and that gives you just as much Armor pen. I feel like those quints could be something else...
