You soak with Olaf during a team fight? I usually use Erik. I'm not any good, so you might be right, but here's my logic.

• Olaf has the most HP and also has the charge which can be useful in a team fight.
• Erik has the lowest HP which means he is a pretty easy target for a death combo.
• Erik is the fastest, so he can get to the lane to soak and/or get to the fight fastest from the lane if it becomes necessary

Thoughts?

My 2 cents I played 5 games at release and came to the exact same conclusion. In ranked I counter them with mainly zeratul because he is more flexible than nova. They are free stacks. The level 1 talent with globes is just amazing But will require a lot of micro. It's quite hard to loose against their stuff when you have played them lol.

Things to do: soak lanes where nobody is with big blue, especially in fight where nobody is on the lane.

In TF: Use everything before ult and position yourself so if you get focused by aoes your team don't take it and also you can flee in the right direction. Then after ult is over use everything on CD try to snowball the fight through autos or gtfo doing your life elsewhere.

Advanced: Keep your viking in a way that they can get together if needed in the common points of interests after lvl10. Try to bait aoes and jumplol to outvalue someone and get on his face.

How I counter: Flank and kill the smallest first. Pick gathering power heroes. AoE burst. Do not ignore.

Pros of the hero: Outstanding dps, xp advantage built in, potential to outvalue cooldows.
Cons: The skillcap required to counter the hero is lower than the skillcap necessary to use it properly.

I really think you should've waited a bit before making this guide because it's the first day of release, your thoughts may change a lot in that time, which might lead new people the wrong way with this build.
