Brain Storm Idea as rare drop from bosses+

The crafting is already in place.

For me: Brainstorms are something of a meh salvage drop. I've only ever used them to craft rare salvage, and there isn't a huge need to do that IMO considering the rare salvage drop rate + fungible salvage on the AH.

Personally, I look at BS ideas like I look at a single converter drop. A nice enough thing to get, but hardly worth getting excited about - unless it's one of my challenge characters.
