The State of Ranked
The state at which League of Legends ranked is at is just ridiculous and is probably the main factor on why people are quitting the game. There is a problem when even professional players and streamers are saying that ranked solo/duo queue is doomed. Some example of these professional players/streamers are literally: V1per, Redmercy, IWillDominate, Tyler1, and guarantee more but just refuse to speak up about a game they use for their annual income. The only fun people have is when they play the game with friends, other than that, ranked is beyond stressful to play in Master+ due to one player being able to bring down the whole entire game since riot wants to create a game too team orientated. I've asked my friends from different ranks, even challenger, and they all think that this season is just dull and too team orientated.
Even if you look at any other seasons, the term "coinflip team" literally came from this season. The popularity of that term literally spiked this season bc of how team-orientated this game is, even though the point of solo/duo queue is to show that you can carry. But you literally cannot carry as hard as previous seasons.
For example, infamous players like RATIRL, APDO, AP0CALYPSE had their peak around last season and before that with their amazing 90% wrs. Nowadays you don't hear about them having incredibly high wrs bc even they can't even carry that hard anymore.
