How to get out of low level bronze

I know how awful bronze is, considering I have been in it for the last 4 seasons. But recently I have gotten out of the lower bronze levels and into the higher ones like b3 and b2 (still low cuz ya know, bronze) but the way I did it was:

Thresh/maining support

Everyone is hating on Thresh because of how much you see him, but honestly, in bronze, you will always get your lane if you main support cuz lets face it, in bronze, everyone is an adc/mid main. Since you get your main in close to every single game, you will (most likely) get good as them,. I played around 40-50 games in a row with thresh and I was out. I know some people hate, even maybe despise support cuz of how boring it is, and how little kills you get, and how you don't get all the glory, but lets face it. There is no glory in bronze. The only people that are watching the game is, that's right, you guessed it, nobody.

If you put aside the glory and the fame that wont even exist, supporting is great. You will help feed your adc to be able to carry, which for me at least, feels amazing and is better than carrying yourself, and now, support is easier than it has every been. Just choose Thresh/Leona and just faceroll the keyboard and your adc is most likely going to get a double kill. Those are just my thoughts and small advice on how to get out of low level bronze.
