What's borderline OP is not his ultimate's CC. It's the only meaningful teamfight CC he has and if his team doesn't have damage he can't do anything.

The OP feature of Amumu is how much damage he deals himself. All 4 of his abilities (passive included) deal a lot of damage and his passive increases this further. He also scales really well from magic penetration and AP, so if you throw an in his build he'll kill people by himself and still tank.
