The "fields of ferocity redux" world quest is currently offering 2154 gold despite showing at most 1253 gold on its tooltip.
This quest isn't even visible to most toons.
I did some detective work and discovered that a) you need to complete the initial questline for it to show up at all and b)
you need an ilvl 400 set for it to award the max gold rewards.
I've never seen an explanation of how this works anywhere, I wouldn't normally cover content as basic as world quests
but the mechanics involved here are far from obvious, if simple once understood.
There are other quests like this. These are worth a LOT of gold collectively to an altoholic.
