I started playing in Cataclysm, where each herb and node has specific locations where they grow. If you need Twlight Jasmine, you go to Twilight Highlands. If you need Whiptail, you go to Uldum. Cinderbloom and Heartblossom? Mount Hyjal.
This made farming infinitely easier and more consistent.
I don’t understand why developers decided to change that method to a “all herbs/nodes everywhere on the map” as it has been since Legion. It makes it so you can’t focus on a specific herb that you particularly need.
There are 4 new herbs, 4 new zones. One should be be tied to a specific area.
