I would like to bring some attention to an issue that I believe is creating considerable unrest in the ESO economy.
I am level 50 in Blacksmithing, Clothing, Woodworking, Provisioning, Alchemy, and 42 in Enchanting. Crafting and trading is my business. I can buy a stack of iron ore from a player for less than 1000 gold most of the time. Refining that stack of tier one ore gives me multiple upgrade items (dwarven oils, grain solvents, and even tempering alloys) and I can vendor the refined ingots for 400 gold, meaning that I am getting thousands of gold worth of materials for around 500-600 gold.
What's more, I have encountered players (who I assume are botters) selling hundreds upon hundreds of stacks of these raw materials for as little as 500 gold per stack. For some time (I haven't checked in the last two patches) there were jute nodes in Stonefalls respawning every couple of seconds, and the botters were farming them aggressively. I suspect that this is the result of a hack or an exploit, and is not exclusive to jute, because those same botters started producing stacks of the other materials (metal ore and rough wood) once the market had become sufficiently flooded with the clothing materials. I also witnessed the prices of these materials fluctuate across the game in sync with the availability of these raw materials.
A small percentage of the population has been allowed to amass vast hoards of upgrade materials, double or triple (or more) their money while undercutting the market by a considerable margin, and reinvest in raw materials to repeat the process.
This has caused the market price of these materials to fluctuate greatly every day, while steadily declining overall. While I have been hoarding my own materials in the anticipation of Craglorn, the knowledge of these mechanics has made me skeptical to buy and sell these materials, as they could be worth double - or half - of their going rate by the same time the next day.
I think that the chance to get the rarer upgrade materials should be reduced for refining the the lower tiers of raw materials, or the source of this seemingly endless flood of low-level raw materials needs to be discovered - or both.
