The Klaxxi are one of the most bizarre reputation grinds in Pandaria, and it has little to do with the mechanics of the process. Your path to gaining reputation remains simple for the most part, completing daily quests with the occasional turn in of reputation-enhancing items. In addition, you'll get the opportunity to complete extra daily quests, depending on what daily hub you happen to be assigned to that day.
However, the story of the Klaxxi is anything but simple. You are referred to with the name Wakener by all of the Klaxxi you encounter -- as far as they are concerned, there is no need to give you another name. And although the reputation grind for the Tillers contains friendly faces and nice people, the Klaxxi are all the way over on the other end of the spectrum.
Which is actually part of the charm, oddly enough.
