Renowned Leatherworking Specialist

Just logged in and this achievement popped. I was hoping the reward was seeing all my lost recipes returned that I lost when I dropped LW for a bit. That doesn't seem to be the case though:(

Logged into my hunter after the 10.0.7 patch went live to be greeted by this achievement. Didn't expect it, not even sure what it means. Yes, that character was a leatherworker during Vanilla and TBC, pre-Cata, but an achievement for that feels a little late coming.

They added a secret way to get all of the old ZG crafting recipes that were removed in Cataclysm (as well as some new recipes for items with the same models as unique drops from bosses/quests), so these feats I think are meant to give a nod to people who had learned any of the recipes the original way. This is the achievement you need, there's guides in the comments there.
