I mentioned in my tweets today that I found some herb changes in the Beta. I've been keeping an eye on the situation for a few weeks now and it looks like things are finally sorted out. Near as I can tell, Plaguebloom has been removed. I was unable to locate any spawns in the vanilla zones. The recipes that used it are now using Sorrowmoss. Just this week I located sorrowmoss in the Swamp of Sorrows. Here's an image I made of the new versions of these recipes:
Another herb appears to be retired as well: Wintersbite. The snowy areas of Alterac Mountains now have "Frozen Herb" which contains a variety of low-end herbs (mageroyal, bruiseweed, etc). I found a second new herb in Badlands (sorry for sneaking in Blizz!) called Dragon's Teeth. Here's a pic I made of it and the sorrowmoss:
You can see here that sorrowmoss is using the old plaguebloom icon and dragon's teeth is using the old wintersbite icon. I'm sure this will be changed in a future patch, but for now it's pretty solid evidence of the switch. Check out this other image I made of the old wintersbite recipes:
All the old recipes that previously had wintersbite are now showing dragon's teeth as a reagent. I'm not completely certain why these changes were made, but I have a theory. Wintersbite and Plaguebloom both have names that allude to a particular location. Dragon's teeth is more generic and arguably can be used in a variety of zones, independent of the climate. On the other hand, sorrowmoss kind of has to hang in the Swamp of Sorrows, so I'm not sure the problem has been solved there. It might have been better to give that a generic name as well... such as slimey-moss or murkmoss or dungmoss. Maybe not dungmoss, heh.
Anyway, that's all I've got for now in the beta. There's really nothing new for professions, but I am diligently checking each day in case something happens :) Feel free to leave a Comment if you'd like me to investigate something while I'm there!
