Since when do the champion reflect the reality of the player ?

ever since i started league , yi and garen were my favourite champions to play with however by the time passes i realised that people call them '' noob champs '' cause they are easy to use and strong ... i stopped playing them to avoid people call me a noob champ player , but then i played a match with a garen who went 25/0 people kept spamming him that he is abusing so op and noob champion , i queued and he got in the same team as me again , however he played azir that time and then he went around 20/1 and he was playing so good , azir is no where close to be an easy champ sure he is op at the good hands . Don't judge people's skill by the champion they are playing , i can be playing garen / zed / fizz or any of those champs who are being hated because of their kits , that doesnt make me a noob ... Faker played Yi , why no one even called him a noob ? Get it already , some people have diffirent tastes some like garen an yi so they play them are you going to blame them for that ? C'mon why is this game like '' pick this champ or be flamed forever '' , Stop making the champion's kit as an exuse of your bad plays if a yi killed then the wrong one is you and not riot games .
