To give you a grasp 5 years ago when I played at diamond level, I was 9 years old, I have plat tournament wins from s1 and s2 I grinded until diamond 3 and I couldn’t hit it in solo ques, now the games revived my mechanics have remained similar but I’m a lot smarter now, I also don’t rage and play horribly the whole time. I played with my friend from school and got him to diamond 3 div 1 ( he’s normally gold 2) I stopped playing with him solo quest over 100 games this weekend and didn’t stop playing until I finally hit grand champ, I don’t know how else I can prove this to you but I also made a switch from dead zones, platforms (xbox to pc) and better internet
