You have not played enough
One of the primary reasons you could be in bronze is as you simply don’t invest a sufficient amount in playing this game to properly measure skill level. If you just have played 20 to 30 games, you probably could get out of bronze if you keep playing for more. It takes a while to receive a correct amount of data for ranking system to correctly judge skill level. That’s why it is imperative that you play sufficient games for your rank to become high.
You are new
A lot of bronze players are basically new to League of Legends. It is not necessarily your fault; you’re just new to the game. Generally less you’ve played that game, less you know about that game and worse you’re at the game. That means that each and every thing is directly proportional to another thing, so unless and until you invest sufficient amount in this game, you cannot become a master. Do not get discouraged though, as you could still get better with determination and a little bit of practice.
Your internet speed is your enemy.
Bad internet could really screw you over & make you lose lots of games. When you log-in and start playing this game, you cannot make plays required to win games and you could easily lose games that you must have won because you keep disconnecting from internet and as a result your opponent is getting sufficient time to play the tactic and attack on your nexus.
