#1. Replacing Hangman Page in the World title match

Another major thing that's clear from the direction of things is that Jon Moxley will be getting a lot more creative freedom and subsequently - an edgier character. With the TV-14 rating, Moxley won't be held back by creative and micromanaging.

Due to the fact that he's simply a bigger star, there's a high chance that AEW might have Adam Page taken out of the equation by Moxley, who will subsequently insert himself into the World title match.
It would also mean that Moxley and Jericho would renew their rivalry after over three years. Despite both being 3 years older, there's no doubt that it would be a better drawing match and a better quality match.
There won't be gimmicks like the "Ambrose Asylum" to ruin it. It'll just be straight up wrestling. Though a street fight-type of stipulation would undoubtedly help!
