The ultimate is pretty overpowered, and the cost makes no sense. At level 6, with just AD runes, masteries, and a single Doran's Blade, he'll gap close with a 130 true damage nuke, while his autoattacks that follow would each do 108 true damage on the slowed target. Pop W as the slow ends, and you have a free kill each time your ult is up and their escapes are not. W would also do 18 damage each second while dueling, and for 3 seconds thereafter.

I dunno about you, but being able to turn each of your autoattacks into a free, scaling olaf E for 10 seconds seems stupidly broken. It'd need to have an insanely long cooldown to be even remotely balanced, and even then, you have your team hang back and avoid fights while you farm.
