It's impossible to leave bronze. Every game I have there is one person who feeds their ass off, or gives up and gets salty. People don't collapse on the most obvious over extensions and objectives. Adcs greed and step in front of tanks in team fights. This is absolutely impossible.
Mysticman892 votesThe reasons you describe are why people who don't belong in bronze inevitably rise even if they're not particularly trying hard.
Remember there are 5 people on the enemy team potentially doing stupid things, while in theory there's only 4 potentially stupid players on your own team, and so on average, you'll rise up provided you aren't partaking in the bronze playstyle.
