World Of Warcraft: Alchemy, Discovery Hotfix

Ok ya'll don't be burning through your herbs and potions trying to make a discovery in Alchemy. Tseric from Blizzard tells us of a Hot fix the implemented. Take a read:

We have been working on the resolution of a serious exploit in game which has led to certain consequences that we wanted everyone to be aware of. A hot fix has been recently applied to the alchemy profession, with regards to discoveries. For the time being, we have disabled all chance of a discovery, until we can implement the proper fix through a patch, as we can not resolve this matter solely with hot fixes. We apologize for the necessary but temporary removal of discoveries, and are working to have them re-implemented with an upcoming content patch.
