There should be more burials in promos. It is the kind of necessary test of strength for the wrestler both in kayfabe and as a shoot. If you manage to have a come back and prove the claims wrong, then you are 10x more credible than you were before. If you fail, then you're back to the drawing board and have to concoct the right recipe for your character to get over. The audience wins by having a show that does not shy away from the truth, and tries its best to not be dull. And frankly, very few people got truly ''buried'' by a promo. It was always the booking.
Wrestlers are too complacent these days, you have to keep people on their toes with sink-or-swim situations, especially in AEW
