In game client surveys?

Obviously the boards only represent a small number of the League community. By nature of it, it also happens to typically be the upset "ermehgerd nerf dis" or "this champ is guttered buff them" people. (Who gets on to say, "wow, this is really going good right now!"? No1. Just like customer satisfaction surveys. You're more likely to get a negative bias...but that's neither here nor there.) We also have to take into account there are much more low elo players than high elo players on the boards.

Anyway, point being that it seems like everyone on the boards pretty much has a universal "stop adding fucking damage to everything rito" mentality. Rito keeps adding damage to things. Whether that be by champion buffs. the new mastery system (that everyone seems to universally hate as well), or champions like Vi being able to point and click immune to cc dive bomb your carry and 100-0 them while being tanky enough to get back out. So obviously rito believes that the people who think thunderloads and warlords and the new mastery system has way too much damage and is dumb are in very small numbers, despite it looking like it's the overwhelming majority on the boards. This also tends to lead people to thinking rito just doesn't listen to them. They'll say, "so i know the boards is extremely tired of Lee Sin being THE meta for 5 seasons straight, but we have evidence saying otherwise."....but then the players don't know what any of that evidence is lol.

So why don't they have in client surveys asking questions about the game. Just a lil pop up box with 1 to 2 questions when you sign on. It would take a total of about 3 seconds to answer a question about "do you think there's too much damage in League?". Then rito can have a very large sample size and report it. Like, well only 15% of players think Lee Sin is a problem. And they can even have accurate opinions from all ELOs. Like, 50% of bronze players think Master Yi is OP but 98% of diamonds think he is garbo.
