That i do know of , just that people who disregard ranks , will play better , not giving a crap if they lose the rank or whatnot.

Think of it like , if you're decent enough , you can get back your rank anytime you want , so having the ranks on top of your head , stressing out about it , will just frustrates you once you are about the lose the match when theres still a chance for a comeback.  I'm speaking from experience , i was once who kept thinking about ranks too , but further down the road , I didn't really care anymore , it just makes me play worst.

Anyway , for people who are really passionate about the game , should watch more Youtube videos , such as WarOwl or watch pro matches , you will learn a lot from those , how to hold a certain position and stuffs.

after you get your rank
