Olaf best top laner?

Just picked Olaf back up recently granted im only Gold IV, but with new items he seems pretty unstoppable. Ive gone 5 for 5 100% winrate so far and plan to keep going, one of the games i made numerous mistakes but it honestly didn't even matter.

Build Core Start Dorans Blade •Deaths Dance •Essence Reaver •Spirit Visage

Then you can basically sprinkle whatever tanky items you want depending on the enemy team and you can murder them all.

Anyway, just wondering if other people noticed this mans strength also.
