What I like about these recipes is the ingredients are much more workable for your typical Jewelcrafter than the 346 jewelry items. We have a higher usage of gems and a much lower reliance on volatiles. I don't know about you but coughing up 75 volatiles for one piece of jewelry is always tough for me. I also appreciate that they incorporated some of the less popular gems like Amberjewel. I've got rare gems piling up in my bank like tribbles, it'll be nice to have a good use for some of the ones that are selling for peanuts currently.
And for those of you still placing bets on epic gems, it's looking like a NO for 4.2 =)
