Different Herald Stacker discussion

Hi All,

I thought I would buck the trend of your standard Herald Stackers and try out a CwC set-up for some lazy auto-targeting Arc action. It is very similar to self-cast but I am running Cyclone and Arc with CwC.

Pastebin: https://pastebin.com/wyp5VFD5

I have completed the "standard" set-up and I am at the point where I am considering upgrade pathways. Most of what I can gather is it is going into -Mana Reserve Jewels, Vitality necklace and other aura's such as Determination and Spider/Avian.

I have played around in PoB and if I get a Vit Neck (With Champion of the Cause) with max Mana res and 6 Cobalt's with Mana res implicit and a Determination Prism Guardian (all of this will be around 80-85 ex), I will be able to fit in Vit, Determination and a 3rd aura of my choice.

I don't mind spending the currency, but I am really struggling to see the benefit of adding the aura's outside of the ES regen. I would lose 72 chaos res and 1k ES to switch out to this. I already have Max phys reduction so Determination doesn't really do anything for me.

I feel like I am missing something simple. Is there anything other than the possibility of using less Heraldry's that I am missing out on? Here is the example Pastebin I have been playing around with.... https://pastebin.com/1Ui1HyJa.

I just don't see the value here as the build currently doesn't have many issues surviving and 1k less es, 72 less chaos res with 1.2k more es regen doesn't seem like a good swap.

I also looked into using Unset rings to pull some aura's off of my gem sockets and to add flat es/es% but the damage loss from taking off COTB is substantial.

Ok rambling is over, make me feel dumb.
