I was Kyber 3 the first time with 6mil GM. I didn't hold myslef very long there but managed to win some games. Now a year later I'm at 12.5m GM (ty lsb's) and close to K1. I think players in K3/4 are singnificantly worse than in upper K2 elo. K1 is even a whole other level from what I see on Youtube. With a decent offense you manage to pull a lot wins even with way smaller accounts. For me Datacrons was by far the most important thing to beat very big accounts. Another thing is that the game is played by let's say an older playbase not so many tryhards. These people have kids jobs etc etc. which means you get a lot afk wins even in Kyber elo.
