This loop is highlighted in a lot of the profession guides as a way to lvl herbalism and mining quickly. As a result it can get BUSY so use the profile in a quiet time.
The bot can sometimes run off into Val' Sharah to chase nodes- i dont see any issues there however.
Loop is the screenshot- obviously you need to be 109-100 to run around in Suramar.
Bot can sometimes get a bit slower when you are full of mana crystals... il think of a way to spend them somehow.
Enjoy!
