Those of us who make Darkmoon decks will no longer have to park our scribes in Dalaran to access the ink trader there, because patch 4.0.6 will bring with it the addition of ink traders in Stormwind and Orgrimmar. Now, aside from changing an alchemist's proc specialization, there's no reason to move any crafting character out of the main cities!
The ink trader used to be the center of every glyph maker's business. Now that the traders only take the somewhat more expensive Blackfallow Ink, they're mostly used as a way to create more Inferno Ink. I also sometimes use them to trade Blackfallow Ink in for lower-level, common inks when I need them for glyphs, but that's only when my stocks of old-world herbs dry up. So far, actually, it's been only Ethereal Ink from Outland.
