I think it would be a great idea if kingsisle would make the creature spells available to wizards as well as creatures. Spells like ice hound, big bad hound, lord of atonement and bonetree lord have really cool animations and its a shame the only time we can see them in action is when we're fighting for our lives.
Even if they can't be learned or crafted, maybe they could pop up in the bazaar from time to time. Just saying.
