[3.0] Champion support HC/SC - Need help with build

Hi,

I'm planing start 3.0 HC with some kind of support, but with champion, not guardian.
At around 30lvl i could start playing only as a support, if i will find someone to play with, giving them two auras and curse, like Hatred and Purity of Elements and Enfeeble. But it is also possible to play with cleave and just respect at 50 lvl.

Please give me your thought about final build and some advice.
