[2021] Am I getting too many kills as support? Blitzcrank/thresh

Been learning how to support. On my main account I’m platinum 1. Been smurfing in silver 4- gold 1.

At the end of a a lot of games my score will be like 8-2-20. I get first blood in like half my games.

I feel a little bad cause people really play out of position and end up getting pulled into the tower.

Should I be doing anything differently?
