#4 Ember Moon

Ember Moon is outrageously athletic.

Exactly.
She isn't doing a whole lot on RAW, and with the likes of Ronda Rousey, The Bella Twins, Sasha Banks, Bayley, and Natalya ahead of her in the babyface pecking order, that is likely to continue.
A heel turn isn't going to help her either; she's too exciting to boo, and would either continue to meander along in her current role (except a change in alignment), or join Mickie James and Alicia Fox as Alexa Bliss' backup.
A move to SmackDown Live offers more tantalising possibilities.
Revisiting her NXT feud with Asuka? A challenger to Becky Lynch? An exhibition match with Naomi or Charlotte Flair?
Certainly a better use of her talents than what is happening on RAW.
