I've been back and forth on what to do with my scrolls. I have three scribes cranking them out and have had mixed results with the cards. The trinkets are hard to move, and the cards themselves sell all over the place. With card prices declining, its unclear to me whether its worth it, especially with many more competitors entering the market and raid progression/trinket nerfs coming.
I'm able to sell Starlight Ink, shoulder enchants, etc at higher margins than the cards, and that's ignoring the price of the scroll. It does help me move large quantities of ink, but it does require a lot of milling to keep up with. I've been considering selling the scroll CD for other's cards, and have been able to at 200g. The other option is the fans, but I don't get motes on my scribes so my margins are less from having to buy the rare fan.
I suppose my question is: What is your current outlook on scroll usage?
