The emissary value does not work correctly, you didnt make 178k. There is nowhere near enough loot in that room, esp with silver. It showed that i made over 500k in emissary gold hoarders, but i think i made around 200k of gold from all factions overall.
These guys show the loot from 3 vaults:
You can easily eyeball that this is not going to be more than 100k even with the full emissary. There is some direct gold missing, but the piles were what, 200? gold on average, so they give something like 5-6k per vault. I think this is in-line to what we got.
Average 4 isle hopes to get to the vault, and the rewards were about 25k per vault. Dragged by the crappy key where majority of the chests were Seafarer, no puzzle, and we managed to loot everything in two minutes :( Gold keys should be around 35k of vault value.
Guess you dont have to make an argument as long as you can recall two people on the different sides of the topic.
