I just smoked and I figured it out.
AEW can't get proper developmental... because AEW is NXT for NJPW
Once a year the main roster stars will show up to fukk around with the youths, but otherwise the separation is firm and no one is ever as over in developmental as they are on the main show.
Old stars go there to try out alignment changes and gimmick shifts from what they're known for, but rarely put over the up-and-coming generation because 'that doesn't work for me brother'
