Under the hood we have all the controls I talked about in the Reddit AMA before launch, a few secret weapons we havent discussed publicly, and were working on deploying some additional controls to further restrain layering from being exploitable.
However, we also want to assure you that the issue is a much smaller problem than some people are claiming. Weve been closely monitoring the effect layering is having on economies and other aspects of the game, and many of the stories we see posted are wildly inaccurate. Weve seen screenshots of banks full of rare crafting materials, which weve investigated and proved false."
