Shaco's E does Magic Damage

Why does it need an AD Ratio? If the Player chooses to go either AD or AD-Dominant Hybrid, then they need to Lose something for that decision. Before the AU, it was Damage on W and E. Now, though, there is no reason to decide. This change needs to be reverted, a Full AD shaco shouldn't be hitting me with Two-shiv Poison for 300+ Damage.
