Wow. Just... wow...
Not jumping down your throat, but, man, what a paradigm shift! I remember when boxing was called "The Sweet Science." Heck, I've read a great deal of material (and republished a good bit of it) from when Boxing, particular amateur boxing, was called (and thought of) as "Scientific Boxing." Very technical in the way people thought about it. Not "complex" per se, but, instead, "sophisticated." I believe that this still holds true. There's a lot of sophistication available in boxing if you apply yourself to its study.
The same goes for wrestling (and most grappling arts in general). There are still some who talk about "scientific wrestling" (usually applied to the older concepts of Catch as Catch Can wrestling). But, instead of being "complicated," they offer sophistication to people willing to delve deeply into the study.
Yes, in both cases, you can simply restrict yourself to the basics. Nothing wrong with that; the basics are a pretty good place because it generally works pretty solid. But there's a level of sophistication which can be built which exceeds the basics, building upon it.
Again, not grumping at you, I just find it a little shocking to my system to see someone describe "The Sweet Science" as "more like a test of endurance and reflex and strength."
Peace favor your sword,
