Darkmoon cards are not easy when you do it multiple times. Unless you are on a server and can buy thousands of stacks easy, its a job to feed a lot of scribes. On my server, there was not enough herbs to get my 6 scribes the ink for a months worth of cards.. i have 69 scrolls of wisdom still. Scribes are good for the start of an expansion and as times goes by and patches raise gear level.. they become less so.
