Thanks for replying Danamoth, the only problem is if you look at the patch notes, it clearly states that it is a 1.2 modifier in the patch notes.

So when he was first revamped, believe it or not his Q was base dmg + 120% attack dmg, now it is base dmg + 20% attack dmg. It was the first value, then sometime ago, I believe mid October or early November it was changed to the latter. I can understand if it was a mistake but still, the notes are the notes and it really was a 1.2 modifier.
Btw, I understand the math, and if what you say is correct, the 1.2 was intended to mean something entirely different then what was posted in the notes.
