#4 Charlotte Flair
Charlotte has a lot of the same issues being a face that Orton does. There is no substance behind her being a face other than that she teams with Lynch and Naomi. The women's division is a better place with her as a heel. She is great as a heel and could provide SmackDown with a top heel in the division; a spot that is currently unfilled.
She badly needs some competition to feud with, and a heel Charlotte against face Becky Lynch or Asuka, if she moves over to the blue brand, would be awesome to watch. She gets the crowd behind whoever she opposes and that needs to be brought to Tuesday nights.
At WrestleMania, The Queen should be getting booed out of the building when trying to use any dirty tactic to end Asuka's undefeated streak.
