I really don't get what the OP is trying to get at, since even watching the best players I can tell their different playstyles, PL and DJT Kung Lao's for example, or PimPimJim and HoneyBee's Dvorah, Gross's Cassie plays much different than KDZs or Gimpy's , same characters but they have their "own" way of playing them. I'm pretty sure I play Kenshi different than Pig's, Blackula's or Ashenars. We all zone, that's what Kenshi does and how he wins matches, at least in balanced, If we are full screen and winning we are not going to try to run, be aggressive to open our opponent up just to be refreshing, only if we really need to.
I think what the OP is referring to is people that are learning imitating other top players which is fine in my opinion, when I started played GL in Injustice I took a lot of stuff from DJT, Gross, Rebelo and applied it to my own gameplan then later on switch things to my own tactics where the way I play the character became my "own". There's nothing wrong with learning from top players and I encourage everyone leveling up to watch and learn everything you can from them and add it to your playstyle or at least consider the option.
