I'm sorry but after a couple of weeks I have only been able to farm up 2 scrolls myself after countless hours in Walk of Echoes and several HKCNM runs. We have now gotten access to the Jeuno Voidwatch and we already had access to the Zilart.
I'm not sure why anyone things it's realistic to let the players control the scroll market. I was lucky enough that of the 2 I got, one was Comet because that is retailing for between 2.5 and 3m on my server.
I don't mind working for my scrolls but with WHM, RDM, BLM, BRD and SCH levelled - I'm really not having much fun right now...
The supply is not large enough to keep these at reasonable prices. Please increase the drop rates.
