When Blizzard add NPCs to assist testers, they are normally temporary objects in the game world (they disappear when the server restarts). Temporary vendors only normally appear for items that are difficult to gain on a test server – perhaps requiring discovery or reputation. In this case there is no content to test that requires this vendor. And all these inks can be farmed effectively by gathering herbs anyway, as on live servers.

Most professions changes never appear in the patch notes. Indeed, I suspect the majority of all changes to the game are never documented by Blizzard.

There are lots of changes lurking in 3.0.8. For example, down in the Underbelly there is a new angler who talks about catching a shark… but 2000 catches and 3 Giant Sewer Rats later, I still haven’t caught anything new. In contrast, the Ink Trader is easy to spot.

About time something was done about Snowfall Ink!
