It looks dumb. Errrrm, being dumb is part of her character. She's clutz, really. You want sailor girl to throw diadem and ridiculously fall in process - she's your best choice. Maybe not every time, but she tends to slip, miss, etc. And by no means she's a pro fighter. As far as I remember, that's the only move that gives of her clumsy nature that vividly.
Lariat is fine in itself, she potentially can do that move, but way less in her character.
