Primary: Tank

Secondary: Mage

I've never seen a SoTAG on amumu, so he's an ap fighter in the current meta, because of his high AP ratios and the fact that early game he doesn't need tank stats so much with the new spirit stone and his Q stunning an enemy before they have a chance to hurt him.

Although, it is true that he was a tank s3.
