I personally don't find her too too hard. I agree she could use a bit of a nerf, but the only thing that really bothered me with her so far is that sometimes she will have another accident right after you change her.
I had her in her aggressive mode chasing me, so I let her get close enough to change her. Then I was only able to back a few paces away before she had an accident again and resumed chasing me. So, perhaps a delay should be added that prevents her from messing right after she is changed? Either way, it's still an interesting experience.
