Speed Running Gnome Vault Key Event

Let’s define “few”
Someone is projecting 500 battles per hour with Dust/3Hawk teams.
Previous estimates put Phoenicia battles at 240/hr.
Given the rough rates of VK (gnome/12) and EVK (vault key/10), and using the data from @Dust_Angel 's post here Vault Weekend data collection - #138 by Dust_Angel

We get the following breakdown (some items omitted), per gnome (directly from gnome, and from 1/12 vault key from that gnome, including vault key from vault key etc.):
Note: Epic Vault Key loot is not included

  • 1.5 diamonds
  • 0.5 event keys
  • 0.5 gem keys
  • 3 gems
  • 4400 gold
  • 62 souls
  • 0.04 major orbs

At a difference of 260 battles/hour, this is what an E5-E8 Phoenicia explorer is missing out on:

  • 32 diamonds
  • 8 event keys
  • 10 gem keys
  • 63 gems
  • 95,000 gold
  • 1336 souls
  • 0.9 major orbs
  • 2.3 minor orbs

Is the E5-E8 Phoenicia rate/hour of 300K-400K gold worth the full list above?
Not for me.
