Well for starters , most of what you ' re describing are parts of what makes up whether or not you ' re good at the game . Knowing the right champions to play , picking your battles as much as you can , and being able to effectively steel yourself against tilt are huge factors in how good you are . Framing them dismissively doesn ' t change that . You seem to not understand how winrates work , however . If you maintain a 55 % winrate on Janna all the way from Bronze to Masters that means you improved massively along the way there , because a 55 % winrate in the latter is literally magnitudes harder than the same winrate in the former . Furthermore , playing a statistically favorable or unfavorable champion is only going to change your final rank by a few divisions at most . Onetricking a 49 % winrate champion if you are on average a Platinum player is not going to slowly push you down to Bronze , and conversely onetricking a 58 % winrate champion if you ' re a Bronze IV player isn ' t going to slowly push you up to Gold . Your personal winrate depends on a multitude of factors , only one of which is the potency of the champions you use . If you ' re interested in climbing first and foremost then obviously you should use the most effective champions you can , but a good champion isn ' t going to push you to an entirely new tier unless you ' re already riding the line to it anyhow .
