The main thing that get me back into like WWE or New Japan, and maybe even AEW would character arcs, which has more or less faded away. To me, that was the best thing about wrestling was a character's story arc an example being how Kenta Kobashi went from a Young Boy always losing to the legend he is now and every step he had to take to get there.
The other thing is have matches that mean something. Most matches now have no psychology or even story behind them. It is just person a fights person b because x reason. Nothing more and nothing less. I want to be invested into a story line or eve a feud, and I want the pain and struggle the hero, or face in this manner, to be showed rather than told. A good example of this recently, who have been Gargano's feud against Ciampa or even Okada's feud with Kenny. A great example would be Bret Hart vs Roddy Piper at WM 8.
