Showing KILL PARTICIPATION in the ending screen summary

On op.gg there is a stat called " P/KILL" where it shows you the amount of kills and assists you have divided by the total kills of your team. This is very important because it shows who is participating in fights and who is contributing to the winning of teamfights. I think that lower level players (bronze - gold) focus too much on the KDA stats shown currently, and that inculding this stat on the end game screen would change some of that "play for KDA mentality" and help players improve overall. What do you guys think?
