I am more than willing to change it, if need be. Could make it have a much shorter range of around 10m base and 20m at max, or make it limited by ways of saying that biological matter is harder for her to comprehend because it isn't static like an inanimate object is, and therefore she can't actually attribute a gravity well or pull to a human being. So at best she'd be able to make it hard for someone to move, or make them hit the ground a bit harder, which might have a negative effect if to were someone like Mammoth because being heavier, for him, equals hitting harder.
