Having said that, is there an AEW mainstay that you can just do away with all together and ship off to ROH to improve. Maybe they stay there, maybe they completely reinvent themselves and come back after a long period and knock it out of the park, who knows.
My votes are Fuego Del Sol, who I'm sure can produce, but he's completely in the shadow of a lot of talent around the same age in AEW.
2nd choice would be The Factory. Nothing against QT but I really have no interest in anything above seeing his stable get squashed on Dark. Hell, they could return in a few years stronger and more interesting than ever.
