Dyes and odd buying behaviour
Likely they are dumping them into the mystic toilet for a chance at higher value dyes
The sell prices for all of those dyes runs from 1.93s to 2.70s, so the flipping return rate (after fees) is 40-90% or more. (Of course, the market will adapt, so some of that profit will dry up.)
For example, last time I checked the data, Silver Lead was WTB =1.01s and WTS = 2.12s, so the theoretical buyer is going to earn well over 50c or so by flipping.
Oh the mystic toilet , I never thought of that
At one point in the past it was actually a way to make gold. But a ton of super cheap fine-level dyes, throw them into the forge, check the prices on the results, sell the greens and high-value blues, and then repeat until gone.
However the cats out of the bag on that one. If someone is buying dyes at 1silver or so in order to forge them, then maybe there’s still profit in it, but I’m not up on the math and statistics enough to say yes or no there.
The expected value of forging 4 fine dyes is about 6.37 silver, assuming all dyes have an equal chance to drop and fine dyes drop 4 times out of 5, masterworks the remaining 1 out of 5. (And published data suggests those are fair assumptions.) After fees, that leaves about 5.42s.
So you can make a profit from forging as long as you keep your cost/fine below 1.35s.
But, as I noted above, the more likelier assumption is that these dyes are being bought to flip. The amount of effort is less and the profit margin is higher (reducing the risk considerably).
Historically, it has often been more profitable to forge.
