If I zoom in to Heidel, I don't think that ALL the locations are correct, would just be too much!
We need gathermate like the WoW addon

I took these notes when I was comparing the drops and drop rates of Diorite to Feldspar. I was Artisan 2 in Gathering at the time when these notes were taken.
I can help provide much more information on gathering drops and drop rates if there is interest!
