Bronze Tier
Bronze is the lowest of the tiers in League of Legends. People in bronze tend to have lower-than-average game sense and mechanical skill, so the best way to climb out of this rank is to have better game sense and mechanical skill (obvious… I know). It’s a given that an effective way to climb out of almost every tier is to be “better at the game,” but that isn’t the only factor involved in each league.
In Bronze, champion choice plays a large part in climbing. From my experiences in Bronze Tier (yes, I also inhabited that elo many years ago), many of the players there tend to play champions that aren’t part of the meta, or the current standard of strong champions for each role. While playing a champion out of the meta is generally fine, in Bronze, many people pick champions that happen to be underpowered, poor for their lane of choice, or overall weaker picks.
An easy way to climb out is to embrace your inner “OP” (overpowered) champion. Because teams in Bronze tend to have underpowered or poorly picked champions, it’s productive to climb this league using smarter picks and stronger champions that allow you to carry your team.
Also, DO NOT pick a champion you are unfamiliar with just to counter the enemy laner. You will almost always be too uncomfortable or unknowledgeable to play well, and most often, you’ll end up losing. Skill > Counters.
Some champions that you may want to think about playing, due to their ease and kit strength are Amumu (Jungle), Riven (Top), Caitlyn (ADC), Blitzcrank (Support), Ziggs (Mid).
