Are the majority of players actually okay with the state the game is in and the boards is just a vocal minority? I see a lot of people on the boards speak out against the current balance of the game, but my friends literally don't care at all and just play the game.
Im under the impression that the majority of people are fine, and the board only consists of the minority.
While it's safe to assume that the boards represent the minority of players, it's not safe to assume that the "silent majority" don't agree (or disagree) with some poster or another on the boards.
Which is part of why Riot doesn't pay exclusive attention to the boards when looking at what people think of various aspects of the game (balance, features, skins, etc).
