I'm pleased with the fix. No, I didn't make tons of money off the market, or anything like that. Heck, I haven't even sold anything today. I did, however, buy a large amount of tanned hides and bones so that I could craft my very first piece of 15k armor for my Necromancer. Once I get some more Elonian Leather (the trader sold out after I bought 7 of them), I can get one of the other pieces crafted. Then, it's off to save a further 15K for the third piece. And that's pretty much all I need...until I buy armor for my Mesmer
Most of my money has come from materials trading. I had a bunch (well, about 74 pieces) of steel saved up (all obtained from salvage), and the "sell" price finally peaked 200gp ea. last night, so I sold 60 of them. Made a healthy chunk of cash even before the fix. Now, I'm waiting for parchment to top 100gp ea again.
And now, with the fix in place, if I really need cash I can sell my two (!) black dyes that I've found, and they'll actually be worth something.
