Simple premise. This thread is about wrestlers who were touted to be big but due to circumstances went to other promotions to hone their craft but could have been big in WWE.
An example to kick off, I could say more but don't want to steal too many examples. Kharma/Awesome Kong. She was on a fucking tear destroying every woman on the locker room until they had them all gang up on her. I understand her falling pregnant screwed things up but it's a great shame she didn't return but at least AEW have her now.
