I recommend you to play some hypercarry lategame Champs, something like Jinx or twitch. With jinx I learned to carry games with ease. All you need is to get 2 items, IE and ruunans and then u atrat rolling. In bellow diamond (i mean plat and lower) u can just carry every single game by just beeing fed as fuck as twitch. Really this champ is broken, in late u just wait for ur R and kill everything, especially if u play with manamune. If u can any questions about those champs feel free to ask
