Although WWE's latest Superstar Shake-up back in April was necessary in freshening up the rosters and creating new rivalries, it can be argued that the pseudo-draft did more to hurt the existing rosters for Raw and particularly SmackDown Live than help them. In fact, it's been well-documented how SmackDown has been worse off since shipping The Miz, Dean Ambrose and others off to Raw and how the program has yet to fully recover from being gutted.
It was recently rumored that a second Superstar Shake-up was set to take place shortly following SummerSlam, but of course, that never happened. We are well into the month of September, and nothing has been announced as of now - but it is evident that changes need to be made to both brands in order for each to have the strongest line-up possible heading into the fall season.
In addition to stars switching from SmackDown to Raw and vice versa, 205 Live and NXT could benefit from an influx of fresh faces as well, and thus they should be kept under consideration during the next Shake-up WWE decides to hold.
Between those four shows, these are the 12 roster moves that are most needed right now.
