Congratulations on getting your JBB. I still remember getting mine both here and on live; it's a pivotal Shaman moment.
I've always loved how it lets you play at being a "battle shaman" instead of always having to hang back and root/rot

Now you just need three more items (epic, fungi tunic, and Torpor) to complete the shaman power quadrumvirate ... and really it's more like two items, as the fungi is more of a stepping stone towards Torpor than something you need after Torpor.
