"I can't climb out of bronze because of teammates"

This is probably the most negative attitude ever and will probably result in you getting worse. For anyone in bronze seeing this, please take it from someone who's been there.

I'm a silver 5 who was placed in bronze 4 this season and managed to go from B4 to B2 in 24 hours. I won 14 out of 16 recent games, almost 4 of those games had afk/troll in them. The funny thing is, I started this game in Season 6 and was hardstuck in bronze for a full year. Looking at it now, my negative attitude was the 1 thing that held me back from climbing. Even a Silver 5 should be able to maintain a 50%+ winrate in bronze, and if you can't do that, you don't deserve silver.

Practice makes perfect, flaming your team doesn't.
