POB: https://pastebin.com/skzzXiBq

Goal is to be a good support for a team, a decent number of auras: Purity of Fire, Vitality, Determination, Purity of Elements, and Tempest Shield. (Items used are actual items I found off the trade site, with some minor-ish exceptions.) For the uniques, I pulled them in via the pob option and maxed their rolls, and for the chestpiece I swapped the implicits for a set of implicits that are theoretically possible to make, as far as I can tell, just will take lots of high tier eldritch orbs. I'm probably missing something as far as defenses go, but I figured, with enough life and resistances, and block, I should be able to handle the other stuff with flasks maybe?

What is the weakest point of defense currently?

Goals were to have lots of auras and be tanky as heck. If there's better ways to do that in your opinion, let me know.
