Yeah I don't think it's a huge change to Void. I kind of love the way Icefraud is buffing/nerfing heroes, it's always in a way that the heroes keep their strengths they're known for.
PS: Filled 2 pages with my hats for the Offering

including a couple of mythical couriers, rares, uncommons... pretty much everything I wasn't using. I wonder what'll come out of it.
