Perhaps this is old news but in case no one has much noticed:
I started warlock yesterday and didn't get herbing as a profession until very late in Elwynn Forest, level 9 or so. So I did what I could and headed out to Westfall with herbing at something like 11 or so. I was delighted to find out that even at such a low level for the profession, I was able to now pick up Earthroot and Blindweed. Nice QOL change for the profession.
