Hexx - Dark/Kin/Soul - Improve my build?

[Hexx]

The Build.

 

This isn't a farming toon or anything like this, this is my actual main that I enjoy playing in a variety of situations. I'm willing to spend all of the influence on him cause I spend more time on him than all of my others combined, so if you have any improvements to the build I would love to hear it. 

 

I have a pretty aggressive play style for a controller. I like to charge right in after the tank with a Fulcrum Shift or Soul Drain and follow up with a Dark Obliteration at the 300% damage cap, possess whoever remains, and refresh speed boosts while the better single target damage dealers clean up. Rinse, repeat.
