There are players who play 20 different champions in ranked that won't be climbing
I have a habit of looking of looking at my match history after every ranked game, and figured out why people aren't climbing. You're playing 20 different champions and 5 different roles!
First of all, you aren't Faker, this guy can play any champion to a diamond skill level in a few games than a person could play in several hundred.
Second, even if you could play every champion to a proficient level, it's not enough to guarantee you'll have consistent wins. You can win 10 games with that one champion one day and lose 10 games the next. I don't want to hear people complain how they aren't able to climb until they
a.) Find a Main, or play 3 or less champions each game b.) Played their main(s) for more than 200 games
My match history has faces, faces of Vladimir. No matter how far you scroll down, you will see him. While i do not know his overall win rate, I can estimate that I can win 4/5 games with him because I have played him so many times.
P.S Overall win rate is low because I took a 2 month break from ranked.
P.S.S To be completely honest, you'll start seeing Annie if you scroll all the way down.
