It seems as though so many posts are getting downvotes for the same reasons they always have - a very loud subset of players that violently oppose change throwing **** onto their keyboards because they think it's being constructive.
As a game is an organic system, made by organic minds and allowed to evolve, the bad WILL be weeded out and the good allowed to flourish. This is necessary for a game's survival. Riot needs their game alive and well - selling out is something entirely different. Selling out is killing off a game, or a music style or what have you for a quick burst of profit rather than a lasting fanbase. Since Riot still has so many places to go and so much ahead of them (it seems obvious to me) they will not make any changes they sincerely believe are unhealthy to the game.
Secondarily, I think Riot's smart about what they do. If they temporarily fail they can easily rebound. If the game can evolve in a bad direction it can just as easily change back. It may suffer for it at first, but will learn from it's mistakes.
Think what you will about the changes. Give your feedback. It's what let's Riot know what's going on. Don't pile horse**** onto the screen because you're upset. That just proves that you do not care nearly as much about the game or about your own enjoyment within nearly as much as you pretend to.
Don't post witty one-liners about how the game's going to hell. Post your fears, your concerns, your true thoughts on the matter. Sincerity is what's healthy to the game. Sarcasm is not.
