AJ Styles lacks psychology. Perfect example have been his matches against Daniels, when they have had a bitter and hate filled rivalry. If you actually hate someone, you are not going to give them hurricanranas, cartwheel kicks, and 450 splashes. You are going to do HIGH IMPACT moves. Body slams, suplexes, punches, kicks, takedowns. But you saw the same shit he always does and it is garbage alot of the time because it doesnt make sense to the story.
People shit all over Cena because he "only has 5 moves" and "always has the same match". The same can be said about AJ Styles and frankly a majority of the TNA roster, which is why they are there and not in WWE. Same reasons why guys in the CFL aren't in the NFL. Just missing something and that something is psychology in AJ's case which is a HUGE deal in WWE.
TNA and ROH generally resort to high paced, flips and stunt style matches that are choppy and seem to have no spur of the moment moves. They set up the entire match prior and don't use the crowd to dictate what happens when. Which is why AJ has seen so much success in those 2 companies specifically. Some people like that. MOST people don't.
