Every single Season is Elo hell

Every bloody season i have the same problem as last time, i get a streak of unlucky losses and so on and so on from trash teams to the most stupid reasons. Like every season i have to put in 500 hours of my wasted time to finally achieve me rightful rank but that takes a ridicules amount of hours to get diamond where you can actually rely on your teammates instead of boosted animals, i post this every season because the matchmaking system is flawed and dynamic que made it worse for solo players thanks riot for another fantastic year.
