Templar - Eldritch Battery (Tank/Aura)

Hey guys, I will probably revisit this build again to tidy it up. But do you think that this would be any good for running as many auras as possible? Not sure how many i could get from this but with reduced mana gems etc i'm thinking that i could run around 4-8.

I'm aiming to be a tank with it too so do you think that i have enough HP nodes?



What is your thoughts and where I should go with it?
