I'd say Hachoo is spot on. Im probably a month behind him in his achievements but i've found myself following the same course. Gundrak to DTK to CoS is my badge farming loop. I've been doing it for a few weeks now. I have pretty much everything i can get badge wise so now im only doing it for rep and the enchanting mats. If you are an achievement whore good luck doing the harder ones, i certainly cant be bothered myself
