I said it appears from what is stated on 3++ that Fliers can no longer fire at ground targets except for Snap Shots. I say it "appears" because I don't have the book yet myself and I'm only going by what I read there in a brief answer. If so, a Faq would be required to allow the Helldrake to fire its Baleflamer at the ground. Don't get too excited. They will probably Faq it, or the Helldrakes will just drop to Hover as there is no reason not to have a swarm of them now.
