The matchmaking is entirely unsatisfying on the weekends
People just bad manner all game, my win rate is way too close to 50 percent on the weekends, and most of the games aren't fun, win or lose. There are toxic players in every match, half the time, I have to report 3-4 of them. During the week, I end up reporting like 1-2 people every 2-5 games. That's a huge statistical difference.
I think Riot should analyze how matchmaking behaves and see if it truly makes sense for it to still work that way on the weekends because at the moment it does not seem to, nor do I ever remember a time when it did.
