That is what wrestling is when it's done right, that's how you get talent over, that's how you add heat to the feud. Two guys going at it on the microphone and not holding back. If AEW did this more often they'd be so much better, but they don't do this type of stuff consistently. More of this please, more promo time to build up feuds.
Mic skills is what gets characters over, MJF is going to come out of this feud with Punk bigger than he ever has been. Again, if this was what took up most of AEW TV instead of spot fest wrestling and long matches, I would be all aboard the AEW train.
