Why are there so many champs that need bans

Xin, Jax, Tahm, Mundo, Malphite, Udyr, Gragas, Akali, Jhin, KogMaw, Zed, Talon, Gangplank.....

Some of these may be personal, but on a real note most of these guys are way too overpowered. Why are all the patches for the LCS and not the actual player. LCS is not REAL league of legends. REAL league is high Silver to low Plat. All the nerfs and buffs are for pro players. When Darius was played in the lcs the next thing you knew he was nerfed to the ground. Xin had no play time in the pros: buffed. Nerfs and buffs are not for the 99% of us who play, its for the 1% of the pros who get the screen time. If they think something isnt strong or weak enough then its fixed, quickly. I am getting real tired of the amout of champions that can carry a game alone. Its so un healthy to the game. and alot of people will say "you can carry with any champion if you are good enough", ya right. play yorick top and tell me out of 10 games how many time YOU CARRIED THE GAME. its unfathomable that it has been going like this for the last 3 years of playing this game. I cant be the only person with this opinion, am i? i neeed claification if im doing something wrong, anything. or am i just seeing things?
