I really like the idea of buying a pack of miniatures for a mage, such as a beast master pack that comes with the mage figure and other figures to represent the creature commonly used by the beast master.  Although I would like to see the dial down life counters, the one thing I would really like to see on the other creatures is a slot to put a number, if you are familiar with the X-Wing Miniatures game all the bases as slots to put numbers so you can distinguish between ships.  You could place the miniature on the board and the card for that miniature off the board and track damage/effects on the card.  The greatest thing about having miniatures is how much it would increase the aesthetics of the game.  I really think it would be a lot easier to get people into the game if they saw figures on the board instead of a jumble of cards, markers, and tokens.

P.S. Wall figures would be really helpful too
