The profession quest is new, updated, more in-depth, longer, more fun, more involving... etc etc. In essence, it is actually a quest now. Talk to that old coot, Training Master Randahl, for details.
*waits for the inevitable "the apprentice form has disappeared from Dundee!" posts in the bugs forum*
.... but please please PLEASE immediately post any bugs you notice in the actual new quest, such as items being rejected or something.
