Dying a lot on my Spark Aura build. Looking to get some help on it.

I've really only played a summon necro this season so far, and for the past couple of days I've been gearing this guy up with some spark+auras gear.

I'm having a lot of trouble not getting one or two shot in t16 maps, even with no modifiers added to them.

The damage feels good, maybe a little low due to the lower crit chance, but overall it still kills pretty fast.

Here's the pastebin. Can anyone help me out on what I can do to improve? The only two auras I'm not running that are in the build are haste/malevolence.
