Nope, 5AA and 1 rabadon is the ultimate build on him. With a void staff if they are stacking MR.

However, you might want to look into building an Abyssal Scepter after boots and tear, then get Rabadon, then a Zhonia's hourglass, then freestyle.

Your E works during the zhonia'q active, so run in, activate it, see them waste their AoE damage on you as your team rips them to shreds.
