Not sure why you used a poison support instead of fire/cold damage or freeze/ignite support. I can only assume you have done so for leveling reasons and are waiting for skills like Flickr Strike or Reave or something.
Yeah, I was basically trying to keep leveling the poison support for when I got flicker strike or whirling blades, since I hadn't reached that point yet. I kind of think an elemental + poison DoT build could be fun, but I don't want to restart again just yet; I'd like to get further than the start of act 2 before I start screwing around with builds again.
