Unpopular opinion: The current state of the game is fine.
Overall, I think the current state of the game is healthy. This is a team meta where solo picks does not matter as much, but the team that co-operates better win the game. I do not understand why people are frustrated at being unable to solo carry games. It's the equivalent of playing a basketball match then complaining afterwards how one person isn't able win the game for the entire team. The problem isn't the game itself, but the community that plays it. Back in season 2 or 3, very rarely do you have people who give up or int. The worse case of trolling was usually last pick who was forced to support. That's pretty much it. In the season 7-8, you have people giving up 3 minutes into the game because jungler hasn't ganked. The final reason is, we only see this game going downhill is because we mature as the game gets older. Most of us started this in our teens or early adulthood, but we shifted from the immature demographic to seasoned veterans. Instead of us being the party to curse, flame, troll, int, most of us came to realize that is not the proper way to behave and are meeting the younger generation that joins the game who don't know better. Ok let's be honest, they know better but at that age they lack the depth to understand. A lot of adults don't gain empathy until their late 20s, which is the core of having a non-toxic team. You can say this is a shit community, but you can't say it's a shit game.
