On one hand I understand the frustration from some of these wrestlers that see the grass greener on the other side and think they can finally get the shot they believe they deserve (or can make things happens if given the chance).
But on the other hand, it's kinda weird they don't see the bigger picture and realize they are gonna end up in an endless loop of dissatisfaction as both WWE and AEW will end up with too much talent if they sign every person that feels they should be booked better. If you are not jumping ship early, you are gonna end up in the same place no matter what.
With Malakai I totally get being frustrated with AEW but at the same time, by the time he could've been pushed harder, Punk, Danielson and Cole were on the roster and he was back to the middle of the line. He could've at least gotten a mini push for a token title defense though.
