Dugi’s leveling guides cover everything from level 1 to 120, for both Horde and Alliance, and any race and class you can think of. You get an addon that you load inside the game which shows you step-by-step how to get to the maximum level in a streamlined fashion. There’s even a waypoint arrow that shows you the direction you need to go, so you’re always on the right track. The addon instructs you which quests to pick up, where and how to do them, when to turn them in, and even other features as well. Dugi guides have been around since 2005, so they’re probably going to be around in the future as well, keeping everything up to date and current.
Fourth, beginning in Mists of Pandaria with the Halfhill farm, and continuing in Warlords of Draenor with various garrison buildings that produced resources, Blizzard has been making trade goods more plentiful and easier to obtain. In Legion, herbs, fish and enchanting materials were so abundant that a very small population of gatherers could supply more raw materials than the economy could consume.
Edit 20 It’s been a week since this post and a lot of people are still reaching out to me with questions which is fine. I have had a few different people reach out to me to help make YouTube videos based off this guide and more info in BFA which I’m more than willing to do. Whoever gets the videos up first I will link them here for you guys to enjoy.
