Hexblast mines build question - can I change these auras or should I keep them?

I was thinking of changing the auras to discipline and purity of elements since this build lacks resists and is a little glass cannon-y, plus I just got a watchers disc es on hit with purity of elements giving more chaos res, is this viable for my build or should I keep the zealotry, skitter bots, vitality, precision, clarity, and what exactly do I need to remove to incorporate it? Or should I just stick to the original build? Thanks! My character obviously is not leveled up yet, but I just am preparing for when he is, I already got all my gear after farming on my templar for a while. I just need to know this so I can decide whether to sell the watchers I identified or just keep it for this build.
