Some might agree and some might not, AJ Styles has been with TNA for 10 years, he has wrestled everyone on their roster on more then one occasion, either he needs to take an extended vacation to allow fans to miss him and be a fresh thing again or part ways with TNA so he can venture into other play grounds like WWE where he can have new fueds with new guys alongs as WWE actually allows AJ to show case his talents and not screw him over like they did with a TNA guy I think WWE had him as Kavol who was Laycools toy pretty much that never won a match, they made him look weak and stuff but he could of did well with the mid card guys.
If WWE took AJ teamed him with Flair as him mentor and let him fued with Ziggler and other guys they might be able to put on some pretty god matches.
Either that or team him with Aces and Eights, maybe interfer with Brooke/Bully wedding but other then that whats left for AJ to do, pretty much nothing.
You're talking about Low Ki who became Kaval in WWE. Can't stand that name; always makes me think of Mortal Kombat.
As for going to WWE, there are pros and cons. Pros: more money, different opponents. Exposure, but not necessarily fame (at least among those who only watch one promotion). The only worthy motivation to go to WWE as it is now would be money and just to branch out/try something new, imo. I can definitely see why people would say that since he's done it all in TNA he should move on to a new place with new opponents, but the idea of changing his moveset, which I'm sure they would make him do even though that's what he is famous for, is preposterous to me, even if it is to learn their "style". Given that WWE's style is rather formulaic at times, that's not an upgrade. It's a downgrade with more money, because lasting fame on a larger scale isn't guaranteed in the long-run if you're gone from the company and the only people who remember you are the ones who knew you before you went. I don't know if
strictly WWE fans ever go, "Where's Kaval?" or bother to look him up. Maybe they do; I don't know.
Other things factor in, of course: dissatisfaction with a company, etc., so I could see it either way, but honestly, I don't think I'd want to watch AJ there. Not if his style changed and they gave him a stupid gimmick. Given how people criticize his mic skills in TNA, I hate to wonder what would happen in WWE. Maybe they'd pair him with their AJ and they can be "AJ & AJ" and skip down to the ring together. Maybe he would be a talented guy who couldn't get over there, especially if he couldn't be AJ in the ring. In TNA, he's over by default, and people love that he's an original.
In any case, that's just me thinking sideways. He's more than earned his break, and I'm sure he's coming back to TNA, but I hope they don't give him another stupid storyline. The man has had enough.
