Actually, the whole point of the post wasn't a personal attack on you or anyone else. . . The point of the post was to ask if the GMs could take a look at the drop rate of greymoss, and possibly up the drop rate, or make it drop elsewhere.
Nowhere in the entire thread did people say "well Grizabella charges insane prices for her items, etc. It was simply stated that since there is a GIANT demand for Greymoss, the price will go sky-high. Why is kedgewater so expensive? Because it's exceedingly rare. I wouldn't sell a kedgewater for less than 150pp. Why? Because you might get three in the course of a 4 hour kedge group. Kedgewater isn't under fire though, because it's not needed as much as Greymoss is in terms of skillups, which is what this whole thread is about, as well as drop rates.
If you look at a supply and demand curve, you'll see that the demand for Greymoss is sky-high, while the supply is very limited. This causes the price to rise, because people are willing to pay an insane amount to get their hands on the goods they want. Take a look at Gasoline, it's the same way. Add greymoss to the market, and the price will come down, and move towards equilibrium.
If the market were to become more saturated, the price would go down. The way to saturate the market more is to up the drop rate of Greymoss. Or make it drop elsewhere, as well as in Dragon necropolis. Hell, I'd go into the WARRENS and farm it if it dropped there.
There is a set price for Greymoss, yes. Why? Because they know you'll pay it. They know it's rare as hell. They know that eventually you'll bite the bullet and take the hit in the bank account.
If you as a retailer will continue to buy your items at a wholesale price, then retail your items at a raised price, the price of greymoss will continue to remain high.
My main point is, up the greymoss drop rate!
