@furyz0r, it really depends on your flask and herb market.
Is Golden Lotus significantly cheaper, than flasks?
Also, it'd help to know the ups and downs of Golden Lotus prices. Today, I've found 100s of it for 230g, while yesterday it was up for 350g and there wasn't much of it. Of course, flask prices had dropped to 235g already.
To be honest, I'm not sure, what will tomorrow bring us. Will lotus get cheaper and more plentiful or will we be able to sell flasks for 350-400g? We'll see.
As usual, it's about buying cheaper, selling higher and not participating, when people post at craft cost (though that's 15-20% profit there at this rate, but I find it unacceptable for the effort).
