A blue poster has confirmed today that ink traders will be added to both Stormwind and Orgrimmar in patch 4.0.6:
“Ink Traders are being added to Stormwind and Orgrimmar in 4.0.6.”
People have been requesting an ink trader be added to major cities since the start of Cataclysm, given that there are no longer portals available in Dalaran and since most people have their hearthstones set to either Stormwind or Orgimmar you’d have to find a mage to teleport you each time you need to craft glyphs and waste your hearth cooldown to get back.
I would be more excited about the news but for me it was never a big hinderance, I have engineering and with the Wormhole Generator: Northrend it was very easy for me to teleport over, I was even considering spending the 8,000g on the ring that teleports you directly to dalaran to save me from flying from storm peaks (since the wormhole generator doesn’t go directly to dalaran), good thing I didn’t now.
For me this is bad news as it may entice more people to get back into the inscription market since this reduces the effort or barriers to craft glyphs but I do see it as a positive change to the game as a whole.
The new ink traders can be found beside the Inscription Supplies vendors in Stormwind and Orgrimmar, you can also find them on the PTR right now.
