Fact
No profession-specific changes were listed for Mining, Engineering, Skinning, Leatherworking, Tailoring, Enchanting, Cooking or First Aid. Related: many profession-made items have a lower vendor sell price; scrolls now trigger a global cooldown; Wetlands node and mob respawns increased and evened out (including Incendicite Ore); the Professions UI art was fixed. New tutorial, detailed Scrolling Combat Text options, Auction House level column and suffix-item stats, and more gamepad support were added. (Oct 15 beta development notes, as relayed by Icy Veins; Blizzard forum post not read directly.)
