Made a build. How'd I do?

Ok, I tried out someones build based on sigils. I found I LOVED Sigils of the Storm. I decided to try my hand at making a build (Support Build) I would like opinion on how I did. Maybe show me how to make it better before I get too involved in it? I want it to work well without having to have good gear, because my gear is gonna be garbage all the way to 40 at least.
