The only way to solve this issue would be to add goldsinks.
Add an option to respec for 500k instead of using xp, increasingly more expensive the higher level and/or more you use it. Add status items that cost ridiculous amounts of gold but look amazing.
These are stupid ideas that wont work for a number of reasons, but they do show my point.
As an economist, this guy has it right.
OP: fixed price will only decrease the price of the looms while leaving the rest of the items, like weapons, armor etc still inflating to crazy levels. it will fix nothing.
This suggestion is right. We need optional money dumps or new money dumps NOT connected to already existing futures. A good suggestion I saw from another thread is adding a level 4 loom for 5m gold or so. It won't hurt any already existing market and hugely hit inflation as thousands of players try to get 5m gold to upgrade their favorite weapon just to dump it out of the circulation. It could fix inflation within a week, maybe less.
A bigger suggestion that I have, which could work without creating huge turmoil in the market: make prices variable according to demand. if a lot of people are buying a weapon, the weapon's price should go up, if nobody is buying it for a lot of time, make it go down etc. This will give incentive to buy weapons at lower prices to sell when the prices go higher. It will, essentially, create a stock market where people will want to give their gold for weapons even when they don't have a direct need for them.
