The problem I see is that Styles is 39 years old in two weeks(Same age as Cena). Reigns/Rollins/KO will likely be here for twice as long, perhaps even more.
You gotta make the most of what you got for as long as you got it. He is the best in ring wrestler you got, he's one of the biggest attractions you got. He should be at the top of the card or close to the top. He won't be in the title match or the MITB match, both of which are the two biggest matches. It looks and feels like he will end up feuding with Anderson and Gallows which isn't very appealing at first glance, I hope that isn't the case or that it is well done.
He should be an exception to proving himself in the WWE. He has had "it" for a while and people inside the WWE saw it when he even wasn't in the WWE(Foley, Ross, etc).
I understand the term bury. It regards in the cards you play in. If you got a push, looked great, then slowly fell down the card for no specific reason or to push a different superstar, aka buried. Losing matches means little unless of course you're jobbing, which probably means you've been buried for a while.
AJ hasn't been buried. It just looks like he's being poorly booked which looks like a step in the wrong direction. No title match(reason being he lost to Reigns twice) and no MITB match(reason being to push KO). He would of made either of those matches twice as entertaining.
Top that off with poor gimmicks with Rollins being heel and Reigns being face. Fans won't buy it for long with Rollins and Reigns looking more like Cena 2.0. With Cena coming back I am interested in how they try to use him, hopefully something different but that won't happen. Same old Cena.
Vince isn't an idiot but he isn't a genius by any means. His product isn't perfect. It is flawed and the cons tend to stand out from the pros, especially with the PPVs. For every pro they seem to have 2-3 cons.
That said I am still a fan but I won't hold back what I think they can do differently.
