Well since Hardy is the top heel AJ wouldn't be in line for the world title and he's above the X-Division title so he should keep the tv title and try to add credibility to it. Stevie's a decent wrestler, but not a title holder right now.
I say have AJ Styles drop it to a well built contender after a period of establishing AJ as a nearly unbeatable champion.
Richards isn't exactly the freshest talent, and has spent most of the last decade being a jobber. See no reason to elevate him at AJ's expense. When AJ drops the belt, it should be to someone with a future that could use the belt to establish himself and get a big win over AJ in the process.
AJ should never lose the TV title. Robbie E should lose to Lethal for the X-Division title, then AJ beats Lethal for the X-Division title. after that, Hardy loses the World title to [insert face] and then AJ beats him and wins that. then AJ and Kaz conquer the Tag division and win those titles. ok.
