I just recently transferred my toon over from Terenas and I brought with me two Formula: Enchant Gloves - Advance Herbalism. http://us.battle.net/wow/en/item/11205
These are specifically geared toward enchanting completionist as they are rare vanilla enchants. There is even some question that on whether they drop anymore. Wowhead indicates that only one, rare, mob may drop it since cataclysm and it is less then 1% drop rate.
If you are interested let me know, we can talk price.
