Rate? You mean who I'd put on a roster if I was kayfabe building a roster for the long-term or who I just like?
I'm not the biggest fan of Nikki, for example, but if I was building a womens brand, she'd be a high sign and the first woman I'd sign because of the merchandise, the tv deal and I think she works the WWE style match better than any of the other women on the roster which is why I think a lot of the NXT style womens matches just don't work on the main brands.
Cena's an obvious gimme just for star power and his freakish regenerative abilities. And I'd definitely get Roman over Seth or Ambrose though he wouldn't be 1 or 2.
