This new "forum" is designed to not allow players to rant about the game.
Do you have examples of why this is the case? Actually, do you have compelling reasoning to indicate there even needs to be a dedicated location to rant about League of Legends?
it seems Riot Games is sick of the community complaining about the integrity of the game.
I'm not sure of the cause, but it's definitely an issue when so many players feel this way. I'm not saying your thoughts here are right or wrong, but enough people seem to feel this way that you would think it would be a high priority for Riot to work on.
an aspect of the game or rules I'm confused about and have nowhere to go to ask.
What question do you have that you are having trouble expressing anywhere on the Boards? I'm not saying you're wrong, by the way, it's a well documented fact within the community that people are unsatisfied with the board layout.
they're turning League into a social media application rather than a game.
What is your reasoning here?
why does Riot change the game based on Challenger +?
Challenger+ is where the game becomes largely about balance rather than player skill. When the players are near the absolute ceiling of play, a 5% difference in the strength of a champion can have a huge impact. In unranked and low level play, a 5% difference in champion strength is drastically outweighed by the difference in player skill so it's almost negligible.
