Hello, this is my build / guide to Olaf, i found out that top lane works best.
Now you're probably wondering Smite... Why? I chose smite because as Olaf i find it best to play top lane and work your way through jungle often rushing into easy ganks. This helps put the enemy off, also having smite whilst lane switching allows you to take blue easier so you can regain mana running between lanes ready for your gank.
The Bloodthirster is a bonus early game if your game goes well! I got fed in a 5v5, no one was able to stop me with this build. The only way i got taken down is by the stuns at low health!

My official ending score was the following :

56/6/3

25.9k

I will update this build often! With more detail on Pros / Cons and Creeping / Jungling + Combos and Farming!

Hope my build helped you a lot thanks!
