I just realized this entire game is based on high risk/high reward
That's why Korean players seem so damn good. Some that come into mind here are Faker, inSec, and Uzi. And based on what I've seen from Korean streams (Cowsep comes into mind, although technically he isn't a 'Korean' streamer, although that is his primary server and where he lives) and the OGN that Riot airs at like 2-3 AM (Night Owl OP).
Basically though, unlike a lot of NA and EU players, Koreans play so risky. Literally every kill in Korea is A) Intentional feeding (Koreans will rage quit in soloQ for almost no reason, EXTREMELY common actually). B) Some made a huge play. C) Some messed up a huge play.
In most cases, an average player would think "Man, 4 enemies under tower with about 1/4 hp, I probably shouldn't dive the four could burst me down," whereas Faker or even some NA players like BoxBox would go "Fuck it YOLO amirite?"
So what I've learned from Koreans is, if you think you might be able to slightly possible barely pull it off, it's worth trying, you're either gonna fail and just look like a normal person, or succeed and look like an absolute god.
TL;DR: Koreans taught me to YOLO
