ISO expert advice on reworking my Golemancer build

Hope you all are enjoying the new league. I am playing standard (for now). Since the league is so fresh and new, I realize most players are too busy to deviate from their rush. I understand. I am hoping there is one or more of you in this group that perhaps is reading this while at work and is bored and willing to help.

I played most all of last league as a decent, but far from optimal minion build. While this build was fun and I was able to clear 164 atlas, it lacked dps and defense to clear end game bosses. Around 1 or 2 weeks prior to league's end, I rebuilt into a golemancer build. When I did, I simply googled, found a build and copied it. A well respected guildie told me the site I had used was inferior and he proceeded to explain why. Unfortunately for me, at that time I did not understand this build's synergy or mechanics very well and quite frankly most of his wisdom was lost on me. Now that I have been playing this build for a couple of weeks, I would like to revisit the topic of upgrading this inferior version of the build into something better. As mentioned however, most players are understandably busy rushing with the new league.

So, if you are still reading this, I will assume you are bored at work and willing to help. 😉

First, I did make some slight changes to the original inferior build to incorporate my two crafted wands - one of which is a trigger wand. While the original build called for 2x cold point daggers, I feel that my 2x wands are equal to or better than using those daggers plus I get the added benefit of trigger. I am simply in love with way the trigger works with this build. I never have to stop moving. All I have to do is hold down convocate and steer my character.

What I am not sure about is whether Storm Brand is optimal.

Also, I am using 4x Carrion and 1 Chaos and 1 Stone golem. I've been toying with the notion of dropping the stone and using 5x Carrion.

I do remember my guildie mentioning something about the conflict in this build's logic as it pertained to it's use of skitterbots and the ascendancy chosen.

Also I wanted to ask how i can get my character menu physical damage reduction higher. It is 70% whereas I seem to recall watching a video which mentioned capping at 90%.

Anyhow, if anyone is still reading, here is a link to this character profile.
