If you're a player who was dynamic queue boosted to Diamond, please read this.
Enjoy it while it lasts. Next season, you're not going to have that crutch of friends to help you. You got lucky at the beginning of the season when Riot didn't put any limitations on premade size above 2. When you're sitting at a much lower elo next season with your diamond borders, the players in your games will laugh at you and call you "boosted". Next season, if you're lucky to even be sitting in diamond 5, that elo is going to be known as the division for boosted players.
