3.19 SRS Necro build draft - looking for feedback

I can't be the only one looking into SRS builds for the upcoming league. I drafted this build: https://pastebin.com/uJPBgLsa and I'm looking for feedback.

Ideas behind the build:

• Have something that would work as a starter (currently no mandatory uniques besides basic AG gear) but allows growth with investment
• Have plain old base dmg scaled SRS and add Unholy Might and Hatred on top
• Use EB to counter raised SRS mana cost and keep using a Blessing for a juicy dmg aura
• Use the newly buffed Haste aura for zoom-zoom :)
• Use the new minion shields instead of e.g. Aegis

With proper gems and gear (nothing too fancy but getting all the gem levels where possible), I have

Bossing Setup: 9.5M DPS

Mapping Setup: 6.4M DPS

With regular gems and less items with + to levels etc it is of course lower but should be enough to get through early T16s I think. Goal would be a smooth mapper that can take care of end-game bosses occasionally after switching 1-2 gems around.

Alternative using Anger and more Focus on fire dmg: https://pastebin.com/dBdUW6SE

I tried to replicate the state of 3.19 using custom modifiers, manually editing items and unspeccing Unnatural strength:

#AG
Nearby Allies have +50% to Critical Strike Multiplier
Nearby Allies have +10 Fortification
You and nearby allies gain 15% increased Damage
10% increased Movement Speed for you and nearby Allies

# Elemental army highest dmg hit exposure
Nearby enemies have cold exposure

#1x Arena Master Spectre (assumed 50% uptime)
10% increased Attack Speed for you and nearby Allies
10% increased Movement Speed for you and nearby Allies
10% increased Cast Speed for you and nearby Allies

#1x Trial Chieftain / Xoph's Favoured (assumed 50% uptime)
You and nearby allies gain 10% of Physical Damage as Extra Fire Damage

#1x Baranite Cleric (assumed 50% uptime)
You and nearby allies gain 10% of Physical Damage as Extra Lightning Damage

# SRS 3.19 buffs
Minions deal 38% more Damage

# Haste Aura 3.19 buffs
8% increased Attack Speed for you and nearby Allies
6% increased Movement Speed for you and nearby Allies
8% increased Cast Speed for you and nearby Allies

What I'd like to improve / discuss:

• Defences without loosing too much dmg
  • Get closer to block caps
  • More armour, having to use a hybrid chest for EB hurts
• Damage
  • Any "minion tech" I'm missing out on?
  • Better spectres than Arena Master + 2x Carnage?
  • Better AG setup that doenst cost tons of ex?
  • Is there anything better than Ele Weakness for cursing?
• Will my AG survive?
• Any uniques I should be looking into?
