the most embarrassing thing for a league player

If you main a champ like 100 something games and you cant even get a tiny lead over someone who plays a different role/ doesnt play the champ they are playing just wow. Unless you are like high elo then its understandable but you should have such more knowledge on every matchup and the champ more then the enemy it should be extremely easy. You look r%%%%%ed flashing your mastery emote missing every skill and losing your lane only to kill steal on a champ you have 100+ games of LOL
