Continuing the discussion from Let's talk gold:
I’m pretty sure those sources of gold are low to allow world quests to be so high without causing runaway inflation (like we saw with Garrisons/Order halls in WoD/Legion).
Blizzard has made it pretty clear with DF/TWW design that world quests and other world weeklies are their designed primary way to get raw gold (something that I think should change, but that’s a different story).
World Quest gold isn’t going to cause “runaway inflation”. 880g for a quest is reasonable. You can do, what, 4-5 of them every 3 days. Let’s say 4000g every 3 days?
Most decent gold-per-hour farms are in the 30,000g-50,000g range. Just casually herbing I was making 20,000g/hr during pre-access. The WoW token is selling for over 300,000g right now, also. Most of the exorbitantly wealthy players I know are still sitting on 5-10mil from WoD garrisons.
Blizzard could force more deflationary gold sinks, of course. Higher repair costs, higher reagent costs, higher auction house cuts. But those “taxes” really serve to pressure poor players more than wealthy ones. Gold sinks like the auction house mount are a great idea, though. Perhaps highly sought-after but expensive transmog could be sold for gold, from Blizzard. Like TCG mounts or T3 armor appearances. Maybe in-game services like race and faction changes can start to be sold directly with gold (instead of a weird token loop).
WoW inflation is a problem, but the game is inherently inflationary. Every piece of raw gold every single players loots at every moment inflates the economy. There are not nearly enough gold sinks to combat it. Multiply is by millions of people playing 24/7 and yeah, it’s going to creep up.
