If you wanna know how to escape low elo in the easiest fucking way possible, play thresh blitz or leona, learn how to push for/pressure around level 2, and all in your lane opponent every damn game. If you wanna get to at least gold, this is the absolute easiest way in the entire game.
If you actually want to learn how to play the game and get better through knowledge of the game etc.. watch higher elo streams and don't just watch what they do but actually analyze it and take every moment as a teaching opportunity.
No offense but if you're in bronze, you suck. Understand this and it becomes a lot easier to get better, because you realize you can get better at literally everything. Easiest time to improve is when you're horrible because there's more to improve on, and its easier to improve on each thing since you're making pretty basic mistakes.
If you have any specific questions add moooose4. I get banned a ton cuz I'm very toxic in game but sit around D1-Master 220 LP most of the season, and do bronze-diamond runs all the time. So fairly knowledgeable about the game and how to play in different ranks in general.
