You know, Ino, Rapha (and I mean Nadal, not the Quake pro
) came to my mind too, when I drew the Tennis analogy. And while I agree that he might be THE proverbial exception to the rule, let's not forget that his trainer(s) worked hard to bring his undisputed, yet rough, talent in line with the anatomical, and physiological requirements of Tennis. And it's not as if he was the first to strike his forehand with such an extreme grip. Also Jim Courier comes to mind, who - as a former Baseball player- stroke his backhand like swinging a bat. When Rapha began his career his style was even more extreme, and doctors predicted a short career due to severe injuries to muscles, and knee joints. While he's still suffering from those injuries on and off, they haven't been nearly as severe as they might have been (i.e. forcing him to quit), had he kept his uncompromised, and idiosyncratic way of playing.
I could give similar examples from legendary piano players too, who worked hard together with their teachers to find a style that meets the fundamentals of piano playing, while harmonizing their natural talent. There's one guy, who neglected this his whole career: Glenn Gould. There are quite a few musicologists that explain his early neurological problems, leading to a stroke, which he died shortly after from, from his malposition at the piano.
Anyways.
What I wanted to say was, that not only Rapha, but many other athletes, and musicans alike have to some degree their individual style. However, they've been studying, and practicing fundamentals for years, that they've become second nature to them. And this is what happens, when something becomes second nature to you: you have them down pat, you are in a position to experiment, adapt, adjust, maybe even depart from the basics a bit, yet sticking to those that simply can't be adapted to you - because they are
fundamental to an area of expertise (sports, science, instruments,...).
Without training, however, you are not qualified to experiement. Sure, "gaming" is a hobby for the most of us. And yet E-sports is growing, and growing, and sooner or later will be just another job profile, like being a lawyer, or playing Tennis, whatever have you. And I'm pretty sure, that one day there will be courses, and training based on a curriculum to become a gamer, much like becoming a hairdresser, chef, or tailor. However, someone has to start gathering data on what's made progamers successful through the years. From the earliest beginnings of E-sports to today. In short, there's got to be a branch of science that examines E-sport to discover its basics. Who knows, maybe todays top competitive progamers will be tomorrows coaches, when after their career they actually start to reflect on the stuff they do/did to become successful. Because apparently they must be doing it right somehow
