RNG didn't pay attention to his opponent and didn't prepare for the game. Before the game, almost no one expected that G2 would beat RNG, because there was a certain gap between the overall strength of the two teams. RNG was stubbornly resisted by G2 team in the competition, and the whole team seemed a little flustered and failed to find a good way to deal with it. G2 played easily and showed all the strength of the team. RNG doesn't understand that pride can lead to failure.
RNG's mentality fluctuated obviously in the game and lost its level in the crucial fifth game. I thought it was a one-sided situation, but G2 had the last laugh. In the fifth game, RNG didn't cooperate, and every player died one after another like a headless fly. 20 18 is too smooth for RNG, giving the players an invincible illusion. When the team is in trouble, they become impulsive and impatient, just like a mess. They lost not to their opponents, but to themselves.
20 18 belongs to RNG, and they failed to get a happy ending. RNG fell to the quarterfinals, which surprised many people, but in e-sports, only the winner will be remembered. G2 performed better than RNG, and they deserved to win. RNG lost because they didn't pay attention to their opponents and games, and their self-confidence exploded.
