Winrates mean nothing.
People are starting to judge how good a champion is by the winrate. "Kassadin and Azir's winrates are under 40%? Now let's complain all over boards about how bad Riot is at balancing their game."
I do agree that Riot does not listen enough to the community. I can also agree with complaints about champions being nerfed too hard. But that has no effect on whether a champion is bad, or unplayable, or not viable, or whatever.
