#2 Fresh match-ups for Charlotte on NXT
Let's be honest here, in the span of her four-year-long main roster career, Charlotte has faced and defeated almost every female Superstar on the roster. It is common to see fans demanding something new from WWE when it comes to her as no one wants to see her have yet another feud with someone like Becky Lynch or Bayley.
This is one of the biggest reasons why the decision of having her go after the NXT Women's title was welcomed by the WWE Universe with both hands. Rhea Ripley vs Charlotte Flair is a fresh match-up which no one has seen before and it allows the Queen to do something new and add another layer to her character.
Moving her to NXT after WrestleMania would lead to her having more fresh match-ups with the rest of the NXT Women's roster, which is currently considered by many to be the best women's roster across all promotions around the world. Imagine her taking on the likes of Toni Storm, Candice LeRae, Bianca Belair, etc. With Belair being heavily involved in the initial stage of her feud with Ripley, she would make for an ideal first challenger for Charlotte, provided she wins the title at WrestleMania.
