It also provides a false metric as someone said that “Oh people are participating! It must mean our idea is a success!” when it is far from the truth.
Small Edit to show how bonkers this rep system is.
I stated earlier that I hit #15 and got between 500-600 rep. Friend just placed #9 and got between 400-500 rep. I will reiterate: Participation Rep on top of Rep you gain in the match with bonus rep on your final rank.
