Looking to climb out of Bronze

You'll start cruising along, winning 7 out of 10 games, 9 out of 10 games, etc then you'll hit this awful fucking wall in Bronze II ish, where you get matched with the worst players you've ever seen. Ones that aren't even ranked, Silver Vs who are worse than Bronze Vs, players who have a 20% winrate which I've never even seen in Bronze V. You'll get demoted, then promoted, demoted, then promoted, and eventually you'll give up and play Overwatch.

That's my story anyhow... maybe you'll have better luck, I pretty much main support so my ability to climb is somewhat limited more dramatically by 4 other people.

I got out of Bronze by playing support, realizing I can't carry so I switch to Lux support. Make it to Bronze II-ish, still can't carry because I'm support. Switch to JG and play Xin, Jax, Yi, etc. Get into Silver, switch back to my main role. Rinse/Repeat. Works for me if I get stuck at a certain spot.
