Hmmm... I never thought about balance. I just played it. Started and re-started until I knew how to make a char of any kind that worked. Feralkin was the only one I didn't like playing; never took one to the end. But I think that was because I didn't like the look of Feralkin, more than anything else. And I didn't like Bestial Magic, either. Although I actually liked the Bestial spirit best, personalitywise! Not oversweet like the Divine, not waspish like the Thought, but quite laid-back and cool! Mostly.
