If you guys think Riot cares about your opinions

You're wrong.

Not that I don't agree with 99% of the people speaking out against the creep mobility and veiger nerfs, etc..

It's just that they don't care because they don't have to. They know that you'll keep on playing, they know that you'll keep on buying those shiny new skins they keep putting out. So why should they care? Money talks. If you people disagreed that much you would cut off their money supply.
