Ranked games help
So ive only had 3 rank games ever played and currently am bronze 4 but i dont know if to continue play rank or draft as theres not many champs im good at and dont really have a main and i dont want to play one trick as if lets say i do rank up if my champ gets banned it will be harder for me to play game also what bothers me is i get flamed for doing 1 thing wrong constantly told "pls uninstall" and "kys bot" which makes me unwanting to play the game so yeah does anyone have tips for ranking up as a new player
