Over the past few days, some upcoming professions changes for Patch 3.2 have been announced, and although they are not as detailed as they could be, several of the changes will have quite an impact.
First and foremost, every profession-specific buff is being upgraded. This includes an Enchanter's ability to enhance their own rings, a Leatherworker's bracer enchants, and more. For a complete list of the current profession bonuses, check out Insider Trader's guide to Profession-Specific Buffs, parts one through three.
These buffs also answer some of the concerns surrounding the upcoming Jewelcrafting nerf that epic gems might be introduced without a buff to the Dragon's Eyes, which, in combination with the fact that these gems will no longer be prismatic, would effectively squash the Jewelcrafting bonus.
Jewelcrafters will also do well to note that they will be able to acquire epic gems by prospecting Titanium. Combined with a Blacksmith's two extra prismatic sockets, this powerful duo is one of the most popular profession combinations.
In addition, Engineers will be seeing some welcome changes to their profession that may make it more appealing. Unfortunately, some of the details have not been made public, so the competitiveness of their self buffs, for example, remains to be seen.
