I think that, at least on Niflheim, the economy is kinda broken. Lots of people just throw away end gear and others sell them for 50-200m, there are no standard prices nor a demand for those items, a few exceptions are Limited ores, Gambler seal-like items (very dif to find), Moon Coins, MVP cards.
I highly suggest a economy overhaul, but that won't happen by nerfing farming spots, maybe rebalancing the prices.
Still, IMO there should be better way to recicle gear, reality is that most mid to late game stuff are worth 10z. Most shadow gear can't even be used before +7 and even if u go and think: "Well, i will just roll 3 of them and try to get a better one" u can't, because 5m for a box that destroys ur gear for a random one is WAY too much.
Even if it takes time, by categorizing the items by Tier you could reprice them and make use of them. You could Tier the item for difficult or demand, maybe both, but by taging a price at an item you could see a revamp on the economy and the grinding spots, therefore no need for closed farming spots (HTF, TT, Jupe, Geffenia, hello?).
