Are they actually scarce, though? Is it legitimate customers, or botted speculators, that create more demand? It seems to me that someone has realized the product is slow enough they can afford to just buy all of them to resell regardless of actual demand. I used to do this with glyphs in WoW and got a lot of hate mail for it. I was buying cheaper glyphs in such quantities that I would delete a good third of them due to warehousing capacity and was still making money reselling other peoples products, and even then I was not selling 100% of my stock. To me this means that demand was actually lower than what the market could bear if it werent for me pinning it at 100% by buying literally everything. It's totally abusive but nobody can do anything about it.
