I'd say anyone with a non-build/specked farming boost. (Ashe, Gangplank, Twisted Fate) since it makes them scale to higher cost items at a rediculous rate without having to do something for it other then pick that respective champ and last hit.

Aside from that anyone with a high teamfight impact beyond proportion. Amumu's and Morgana's Ultimate ability are the perfect example to these. Nunu and Galio's Ulti however are fine, since they can't perform any other action during that time and their ulti effects can be broken. Being able to stun an entire tem for 2 seconds while still laying on the hurt is just too much.
