How to get Silver from Bronze.

So my teamate was terrible. Fed an ekko like 8 times by 15 mins and as a result he focused and killed me from back line. They were crushing us. Illaoi kept feeding and getting caught out for no reason. Further feeding a jhin. I wasnt fed due to a safe corki mid and took exhaust for a yi... this saved me 4 times from yi and shut him down. Instead we funneled kills to sivir took objectives and won :) they even got Baron. But we didnt rage. We encouraged good plays and i shot called. You know what happened. An under fed ziggs helped win the game after we team fought well after i noticed yi split pushing. Deleted corki or caught leona out. So dont rage, play smart and win
