#5 Should not happen - NXT gets involved in Superstar Shake-up

NXT is without a doubt the best show produced by WWE and the developmental territory always beats the main roster in terms of storytelling and in-ring action.
WWE can always introduce NXT as their third brand and have them fight with RAW and SD Live for brand supremacy but involving them in a Superstar Shake-up will be a step back for the yellow brand.

NXT develops the superstars in order to give them a dream career on the main roster but not every NXT star has emerged successful. Also, NXT is the place where new signees are given in-ring training and match practice and involving NXT in the superstar shake-up may force the WWE from keeping its new signees away from TV.
So, to conclude NXT can be used as a third brand of WWE but at the same time, it should retain its position as the developmental territory. If NXT gets involved in the superstar shake-ups, there will be no such thing like main roster and developmental territory, which may hinder the fans' excitement for the product.
