Faster, snowball-y games are leading to more toxicity
Now a single person's mistake is more impactful. Which causes the team to rage at them. Team advantages/disadvantages are more drastic at the 15 minute mark, which leads to hopelessness. Which leads to feeders. Which others have to endure because it's too early to surrender.
Some of the most fun games that I've won or lost were 45-55 minute games that could have gone either way. And they were fun because my teammates and my opponents never gave up.
The current game state leads to more frustrations and hopelessness, and is causing more people to give up and give up sooner.
Riot, I bet if you look at your data you would see that toxicity is on the rise in this game state. Please do something to level the playing field and stop encouraging stomps. It's not fun.
Perhaps look into strengthening towers or removing the minion buffs that are based on level advantage?
