Iron Grip Wand Templar?

Hi everyone, I just got into the beta and I hear we are quite close to a patch, which most likely means a wipe and many changes, but I'd be interested in your opinion about a build I'm working on.

So far, it looks like this.

Keep in mind I don't have the slightest clue about what works and what doesn't in this game, but I'd still like some input about the feasibility of this kind of build as I really like the cowboy style it gives to characters.
