Whinging On The Boards Alone Will NOT Provoke Change
Minimizing player loss is of paramount importance to Riot. After all, it's the main reason we see cherished modes like URF bastardized into inferior versions.
If player count dropping makes them ruin a near universally loved mode, why aren't they quickly reworking all of these nonsensical changes? Why are they not shifting the meta away from 'who wins botlane' like the community is requesting? It's pretty simple: People are still playing the game.
In fact, the vast majority of people on this board complaining about the balance (with highly upvoted threads) are still playing the game. You need only check their match history. If you actually disagree with the changes and find the current meta unenjoyable... STOP PLAYING THE GAME!
Put your money where your mouth is like I have. I haven't touched this game in months and refuse to do so until Riot decide to take game balance seriously.
If you want change, I recommend doing the same.
