Riot doesn't think the current meta is a problem

"Here's the thing, I do think communications would help here, you'd be able to understand exactly why we're okay with Pantheon sitting on "54%". If we talked more pro-actively about our goals and plans, maybe we could've dropped a line that we're taking a look at Bramblevest. On things like Cho, we'd get cases were we double-down nerfs on items and champs, no need to go there. To be honest, from all the things I'm seeing you talk about, it could be bounced back to how the meta shifts a lot and not everything will be relevant all the time." -Luqizilla (Rioter)

They're saying that they're fine with all this shit, and that clearly they haven't shown why. Just imagine this, without third party statistic websites, there would be zero information to prove how wrong Riot is. Keep in mind, this is part of a reply to a thread making fun of Riot communications about balance.
