Quest showed up today out of the blue after 3 weeks of checking daily. I am so happy its working!
Quest does not appear. Not sure what is needed to make it appear. I am exalted with The Klaxxi for years and just came back to get the achievement but it requires this quest. Their are a few others in Wow-head having this issue and I was surprised to find no bug report. I do all the dailies not sure if it is needed but I do them anyway to see if the quest will pop up. Nothing now for 3 weeks.
