Matches and work rate are more important in WWE these days, it doesn't matter how she looks if she can't keep up in the ring, remember how WWE tried to Make Alexa and Lacey Evans happen? And she's not going to be in the ring with the likes of Bayley, Bianca and Becky all the time, so she'll have to carry herself and her opponent if she's in there with someone less skilled.
I don't see the need to rush her to the main roster.
I don't see her touching Bianca ring wise, Bianca is far more athletic and smooth compared to what we've seen from Jade.
