#3. & 2. The Revival - Asked for their WWE release multiple times

Post-WWE, The Revival, or FTR as they're now called, are exactly where they belong in AEW. The Revival are perhaps the only example of Superstars on this list who asked WWE for their release on multiple occasions.
The Revival were vocal about the fact that WWE paid no heed to tag team wrestling - something that they prided themselves in. And there was no denying that since their formation in NXT, Cash Wheeler and Dax Harwood have been among the best tag teams in the world.

For the duo, it wasn't just the fact that they were underutilized, it was the fact that WWE mistreated the entire tag team division - hardly even featuring the reigning Champions at the time. It reportedly boiled over in early 2019 when then-Champions Chad Gable and Bobby Roode weren't featured on RAW, leaving the duo fuming and asking for their release, per Pro Wrestling Sheet.
The Revival desperately wanted to leave WWE and they got their way out in the mass release of April 2020 - finally getting the opportunity to join AEW, a promotion where they're sure to succeed.
