just to hammer home the point... when you drop a tradeskill you forget everything about it.
skill level is set to 0 zero
all patterns/recipes/schematics/etc are erased and gone for good till you relearn them from a trainer or drop item
if you have choosen a particular path on said tradeskill that path will STILL be recorded ie. you cant: learn gnome eng, then decide ya dont like it, drop eng, and get goblin eng. same goes with the blacksmith and leather working paths.
