#5 Should Be - Nia Jax

Nia Jax won the battle royal at WWE Evolution to become the new #1 contender for the RAW Women's Championship. With Ronda set to battle Becky Lynch at Survivor Series, to be a part of team RAW is the best thing Nia Jax could do during the inter-brand warfare.
She could also emerge as the sole survivor from the women's match, which would provide her a ton of momentum before she faces off against the undefeated Ronda Rousey.
To leave the Irresistible Force off team RAW would be a serious mistake. If the WWE Creative does so, she may not prove to be a credible challenger for Rousey's title. Given the booking she received at Evolution, there's no chance that she would not be a part of team RAW at Survivor Series 2018.
