I've used WoW-Pro for years and in WoD, Legion and now BfA it's been awesome for just going on auto-pilot and working your way through a zone. It has 3 levels of depth you can set, so you can set it to just do 1) the main story, main points of interest and rare mobs and treasure that aren't far off the beaten path; 2) every quest with a more thorough dive into the side stuff; 3) absolutely everything.
Extract ConsolePort to Interface/Addons. The addon can be downloaded through the Twitch app too. Make sure the addon is enabled when you log in to the game. Install WoWMapper and connect the controller to your PC via cable or bluetooth. Make sure the controller is recognized by your operating system. Log in to the game and make sure ConsolePort is enabled. Now it's time to choose your controller layout. Grats, you can now start playing the game with a controller. (Optional) Enable Action Camera for extra immersion by typing /console ActionCam full, /console ActionCam basic or /console ActionCam default, depending on whichever you prefer most. You can turn it off by typing /console ActionCam off command.
