how to win in d5 and below

do not pick the following champions (you'll thank me later)

Lee sin Fiora Ezreal Nami Gnar Tf Kalista Akali Katarina Azir Ahri Elise Gp Zed

Just the top mostly played champions. Seriously every time someone in any of those elos play those champions its like watching a horror movies its just horrendous play. Too hard for these skill levels Ive had to lose so many games because someone is on something they cant play and just feed/are mostly useless its unreal. That and people play too many champions you dont need to play every champ in the game in ranked.
