Do you think my build is worth it?

I've been playing doctor with a cool build which has done good and done nothing in different games.

Dark devotion/Coulrophobia/Overwhelming presence/Infectious


When i find the obsession, I hit them then leave. They are now 50% slower at healing and 100% item loss. I down someone everyone near the obsession screams! If I don't, I save and use my static blast before Dark Devotion runs out and see everyone near obsession.

Thoughts?
