Well, yes and no.

It makes sense for her to have to get the mass to transform, I just didn't take it all the way and so it is mostly magical.

It also keeps her power in check because there is theoretically no limits as to what she could transform into.[/quote]
I usually apply a certain amount of logic to magic, but not usually this sort. Still, it's certainly one decent way to balance this sort of thing.
