I play as a mage and I think it's rather useless turning ppl into sheeps as you can't win that way. When the opponent is in sheep form he is sure to get to full hp and there's just no way this will help the mage winning a duel. I dueled a druid that was my lvl and it seems the balance is quite good, I won by about 50hp. If I had turned the druid into a sheep as I got low hp then I'd be sure to lose since he'd get full hp vs my 50, so it's simple stupid using the sheep spell for dueling. Ofcourse if you want a draw then it's ok........
