Ranked Partner

If you want to look at my match history, then go ahead. I can play any role MID>ADC>TOP=SUP>JG. I just played 4 or 5 ranked games in a row, and am completely disgusted with how my team played (decision making etc...). The only thing that i think i could've done better was my build. I dont understand how i can carry, I play a bunch of games assert myself as "shotcaller" (get my team to trust me), and no matter what someone will go out and die, and throw the game.
