New Season, same bad plays

27/13/23 in my last 3 games but because My team wont follow and group, lost all 3 games. 1) 15/6/11 2) 6/3/10 3) 5/4/1. New season yet still low elo will not learn basic game play. Gonna be another climb from Bronze after losing those 3 games even with good KDAs and good CS. Can someone show me how to carry a 4v6 because there is always the 1 person who goes for double digits deaths. 1) top laner and jungler 10+ death 2) jungloer 13 deaths, jungler and top lane zed 2 kills each 3) 0/7/0 Karthus, 1/8/2 Mundo. Every game 4v6 tonight, I need some advise on how to carry this.
