On behalf of all the more sensitive and 100AP people who do not pk, I believe such a feature may result in much negativity, especially towards the people striving to become better; more deaths than kills will result in major self esteem issues.

You know how newer sparrers get when they can't win a spar, very depressing, Indeed.

If implemented there will most likely be an option to hide deaths. Surely some people will be proud of their pk/d ratio, but many others may not, if not care.
