With glyphs sold in the Shaman Class Hall, you really need to fix the bugs preventing people from doing / completing the Shaman Class Hall quests. I know there are many issues, but for example mine is:
I have completed the quests:
A Ring Unbroken (id 39746)
The Elements Call … (id 41335)
but not the quest A Ring Reforged (id 40225)
However, after the quest The Elements Call, I have left the Maelstrom (Shaman Class Hall). I now have no portal to the Maelstrom / Class Hall in Krasus’ Landing in Dalaran, so I can not get back to the Maelstrom to accept/complete A Ring Reforged.
