I feel like people just blame the LCS for everything Riot does wrong.
The same champions see play every game? It's only because Riot wants them in LCS.
Damage Creep growing in League of Legends everyday? That must have been caused by LCS, because everybody knows that more damage = more views.
My cat is gone? Definitely LCS. 
Why does everyone hate on LCS if something balance related happens? I'm sure sometimes Riot tries to force certain champions into the spotlight, but most of the time a champion is used in the LCS is because a team has recognized the champions strengths and uses it because it's good.
