Hey friend! You sound like you're having a problem and need assistance!
A little bit about me: I used to be Bronze 5. Back in the ELO system, I was at 700 ELO (that's so low, it's below Bronze 5 right now). I was there because my teams sucked. Because no matter if I did well, my team would throw. I was this for 2 seasons.
Now I just hit Diamond.
Let me tell you, it's not your team. I promise you. No matter how bad it looks, it's not your team holding you back. YES, there will be games where your team throws. But that doesn't happen every game. It's your gameplay that is Bronze 5.
Please don't just ignore what I'm saying and continue blaming your teammates for where you are. I want to help you:
Go to www.replay.gg
This website lets you watch the replays of your games. Watch a recent game that you thought was your team's fault. When you do, don't move the camera from yourself. Watch every mistake you make. IGNORE everything your teammates did in that game, and ONLY pay attention to yourself. If you actually stay calm and analyze it, you'll be surprised at how much you're messing up.
This will help. I promise. You can carry yourself out!
