One could argue dean ambrose but they'd be wilfully ignoring the many months as WWE champ and ppv main eventer and looking at the last few months of his time at WWE.I haven't watched wrestling in years so this is a real question has anyone who WWE ignored or misused proved them wrong yet by becoming some revelation in AEW? Please no match quality stuff, I mean are they a star there like they weren't in WWE?
Other than him quite arguably...no.
