I always thought it would have been a cool alternate fighting form for Ax. Not sure why. Although he seemed to be disgusted by the idea of fighting with a mouth, so whateverz.
Cassie's wolf kind of bothered me sometimes. It just seemed a little strange they'd risk letting her fight in such a lower-powered form, y'know? Like when there's a skirmish with some controller cops, or even security guards or whatever, I was always thinking like "one bullet...one bullet..."
It just seemed odd. Sure, a wolf is dangerous enough if you're confronting an unarmed human. But even a couple of mallcops or whatever with low caliber pistols could dispose of one pretty easily.
