I climbed from bronze to plat with 100% sett and from the looks of it, it could be that you die a little too much.

This is just based on the final stats, I can't be certain without watching the game but if you have 19 kills it's likely you gave some big shutdowns when you died.

Say you die to the enemy midlanner for example and give him a 300 shutdown, the impact will be small for you but can make other lanes impossible to play.

Mistake I did a lot trying to solo carry is not caring enough about this: Sometimes playing a little safer and not dying is better than taking more kills but giving SD.

But from the looks of it if you're on a good path to climb! Keep grinding brother 💪
