I don't know what to do to win a game, in the game with smolder i was 1 win from silver, now im bronze 3, i always have a teammate with a score like 1/8 and the support who engage in lane when i have 200hp and then flaming me because i didnt follow him. Anyone has any idea how to win a game as adc in bronze?
